A Friendly Teacher’s Guide with Real-Life Examples & Step-by-Step Solutions
Target Focus: Math Tutor in Richmond Hill | Grade 10 MPM2D & Grade 11 MCR3U

💡 A Friendly Message from Your Math Teacher: Welcome! Math can sometimes feel like a series of abstract rules, but it is actually the language we use to describe patterns in our world. In this guide, we connect functions, graphs, and algebra to simple real-life stories. Let’s make math enjoyable and easy to master together!

1. What is a Function? (The Vending Machine Example)

Imagine you are standing in front of a snack vending machine:
• Input (x): The button you press (e.g., B4).
• Output (y): The snack that drops into the tray.

When is it a Function?
Pressing button B4 always gives you a granola bar. One button gives you exactly one predictable snack. That is a function!

When is it NOT a Function?
Pressing B4 gives you a granola bar today, but potato chips tomorrow. If one input gives two different outputs, the machine is broken—it is NOT a function.

Can two different buttons give the same snack?
Yes! Buttons A1 and A2 can both give pretzels. That is completely allowed in a function.

Worksheet Solutions: Section 1 (Tables & Sets)

Worksheet Problem	Is it a Function?	Teacher’s Explanation
1. Set A: {(-3, 4), (-1, 2), (0, 5), (2, 4), (5, 1)}	YES	Each input (-3, -1, 0, 2, 5) is different! The repeated output 4 is completely allowed.
2. Set B: {(-2, 1), (1, 3), (1, -4), (3, 7), (6, 0)}	NO	Input 1 produces two different outputs (3 and -4). One input cannot have multiple outputs.
3. Table of Values: Inputs: -4, -2, 0, 2, 4 Outputs: 16, 4, 0, 4, 16	YES	Every input maps to one predictable output (following y = x²).

2. The Vertical Line Test (The Time-Traveler Rule)

To check if a graph represents a function, use the Vertical Line Test (VLT)!

Real-Life Analogy: Think of the horizontal x-axis as Time (2:00 PM) and the vertical y-axis as your Location (School or Home). You cannot be in two different places at the exact same second! If a vertical line touches a graph at more than one point, it means one input has multiple outputs, so it is NOT a function.

Figure 1: The Vertical Line Test. Red dotted lines show where relations fail.

Worksheet Solutions: Section 2 (Vertical Line Test)

Graph Type	Function?	Teacher’s Explanation
4. Graph 1: Circle	NO	A vertical line down the middle cuts through both the top and bottom. Fails VLT.
5. Graph 2: Straight Line	YES	Any vertical line drawn touches the line only once. Passes VLT.
6. Graph 3: Sideways Parabola	NO	A vertical line crosses both upper and lower branches. Fails VLT.
7. Graph 4: Absolute Value (V-shape)	YES	A vertical line touches the V-shaped graph at only one point anywhere. Passes VLT.

3. Graphing Functions from Equations

Graphing is just like following a recipe: pick your ingredient (x), calculate the output (y), plot the points on your coordinate grid, and connect the dots!

Problem 8: Linear Function f(x) = 2x – 3

• Table of Values: (-2, -7), (-1, -5), (0, -3), (1, -1), (2, 1)

Problem 9: Quadratic Function g(x) = x² – 4

• Table of Values: (-2, 0), (-1, -3), (0, -4) [Vertex], (1, -3), (2, 0)

Problem 10: Absolute Value Function h(x) = |x + 1| – 2

• Table of Values: (-2, -1), (-1, -2) [Vertex], (0, -1), (1, 0), (2, 1)

4. Function Notation: The Kitchen Blender

Think of f(x) as a blender named ‘f’. The number inside the parentheses is the ingredient you drop in. The equation is the recipe!

Worksheet Solutions: Section 4 (Evaluating Functions)

Given Base Functions:  f(x) = 3x – 5  |  g(x) = x² + 2x  |  h(x) = √(x + 9)

Problem	Step-by-Step Friendly Recipe	Final Answer
11. f(4)	Drop 4 into machine f: 3(4) – 5 = 12 – 5	7
12. g(-3)	Drop -3 into machine g: (-3)² + 2(-3) = 9 – 6	3
13. h(16)	Drop 16 into machine h: √(16 + 9) = √25	5
14. f(-2) + g(3)	f(-2) = 3(-2) – 5 = -11 g(3) = (3)² + 2(3) = 15 Combine: -11 + 15	4
15. Find x if f(x) = 13	Work backwards from output 13: 3x – 5 = 13 → 3x = 18	x = 6
16. Evaluate g(a + 1)	(a + 1)² + 2(a + 1) = a² + 2a + 1 + 2a + 2 = a² + 4a + 3	a² + 4a + 3

What is the Quadratic Function Transformation Formula?

Quadratic transformations modify the parent parabola f(x) = x² using the standard vertex form equation:

y = a(b(x – h))² + k

• Vertex Location: The new vertex of the parabola is at (h, k).
• a (Vertical Stretch / Compression & Reflection):

• If |a| > 1: Vertical stretch (parabola becomes narrower).
• If 0 < |a| < 1: Vertical compression (parabola becomes wider).
• If a < 0: Reflection across the x-axis (parabola opens downwards).

• h (Horizontal Shift): Shifts right if h > 0, shifts left if h < 0. (Note: y = (x – 3)² shifts right 3).
• k (Vertical Shift): Shifts up if k > 0, shifts down if k < 0.

Parent Function Baseline: f(x) = x²

---

All quadratic transformations originate from the parent graph y = x² with its vertex at (0, 0) and axis of symmetry at x = 0.

Parent x	-2	-1	0	1	2
Parent y = x2	4	1	0	1	4

Step-by-Step Quadratic Transformations

PART 1: Vertical Shifts (Transformations on the y-axis)

Guided Example: Graph y = x² – 3

• Shift Direction & Amount: Shift down by 3 units (k = -3)
• Vertex Location: (0, -3)
• Method: Subtract 3 from all parent y-values.

x	-2	-1	0	1	2
y = x2 – 3	1	-2	-3	-2	1

Problem 1: Graph y = x² + 2

• a. Shift Direction & Amount: Shift up by 2 units (k = +2)
• b. Vertex Location: (0, 2)
• c. Table of Values:

x	-2	-1	0	1	2
y = x2 + 2	6	3	2	3	6

PART 2: Horizontal Shifts (Transformations on the x-axis)

Problem 2: Graph y = (x + 3)²

• a. Shift Direction & Amount: Shift left by 3 units (h = -3)
• b. Vertex Location: (-3, 0)
• c. Table of Values:

x	-5	-4	-3	-2	-1
y = (x + 3)2	4	1	0	1	4

PART 3: Combined Shifts (Both Axes)

Problem 3: Graph y = (x – 1)² – 4

• a. Horizontal Shift: Right by 1 unit (h = 1)
• b. Vertical Shift: Down by 4 units (k = -4)
• c. Vertex (h, k): (1, -4)
• d. Table of Values:

x	-1	0	1	2	3
y = (x – 1)2 – 4	0	-3	-4	-3	0

PART 4: Reflections Across Axes

Problem 4: Graph y = -(x + 2)² + 1

• a. Parabola Opens: Downwards (reflected over x-axis since a = -1)
• b. Vertex (h, k): (-2, 1)
• c. Describe All Transformations: Reflection across x-axis, horizontal shift left 2 units, vertical shift up 1 unit
• d. Table of Values:

x	-4	-3	-2	-1	0
y = -(x + 2)2 + 1	-3	0	1	0	-3

PART 5: Vertical Stretches & Compressions

Problem 5: Graph y = 2x² (Vertical Stretch)

• a. Transformation Type: Vertical stretch by a factor of 2
• b. Shape: Graph is narrower than parent graph y = x²
• c. Table of Values:

x	-2	-1	0	1	2
y = 2x2	8	2	0	2	8

Problem 6: Graph y = ½x² (Vertical Compression)

• a. Transformation Type: Vertical compression by a factor of ½
• b. Scale Factor: ½ applied to y-values (graph is wider)
• c. Table of Values:

x	-4	-2	0	2	4
y = ½x2	8	2	0	2	8

PART 6: Master Challenge (All Transformations Combined)

Problem 7: Graph y = -2(x – 3)² + 8

• Step 1 (Vertex): (h, k) = (3, 8)
• Step 2 (Reflection): Opens downwards (reflected over x-axis because a = -2)
• Step 3 (Stretch / Compress): Vertical stretch by a factor of 2
• Step 4 (Table of Values):

x	1	2	3	4	5
y = -2(x – 3)2 + 8	0	6	8	6	0

Frequently Asked Questions (AEO Section)

How do you find the vertex of a quadratic function in vertex form?

In standard vertex form y = a(x – h)² + k, the vertex coordinate is directly given by (h, k). For example, in y = (x – 3)² + 8, the vertex is (3, 8).

What causes a parabola to open downwards?

A parabola opens downwards when the vertical stretch factor a is negative (a < 0). This represents a reflection across the x-axis.

How do you tell if a quadratic function is stretched or compressed?

If the absolute value of a is greater than 1 (|a| > 1), the parabola undergoes a vertical stretch and appears narrower. If |a| is between 0 and 1 (0 < |a| < 1), the parabola undergoes a vertical compression and appears wider.

Introduction

This guide helps students learn exponent rules in Grade 9 Math and prepare for EQAO-style assessment questions. It mirrors the structure of the Exponents Worksheet (Grade 9 & 10) and explains how to teach each section.

What Are Exponents?

Exponents are a shortcut for repeated multiplication. For example, x³ means x × x × x.

Key Exponent Rules (as in the Worksheet)

1) Multiplying powers with the same base: a^m × aⁿ = a^m+n

2) Dividing powers with the same base: a^m ÷ aⁿ = a^m−n

3) Power of a power: (a^m)ⁿ = a^m×n

4) Power of a product: (ab)ⁿ = aⁿ bⁿ

How to Teach the Worksheet

Part A – Basic (Build Confidence)

Goal: Practice one exponent rule at a time.
Teaching tips:
• Point out the base (same letter) before doing anything.
• Decide whether the question is multiply, divide, or power of a power.
• Apply the rule and simplify.

Part B – Intermediate (Combine Rules)

Goal: Combine coefficient multiplication with exponent rules.
Teaching tips:
• Multiply numbers separately from variables.
• Add exponents when multiplying like bases.
• Subtract exponents when dividing like bases.
• Distribute an outside exponent to every factor inside brackets.

Part C – Advanced (EQAO-Style Practice)

Goal: Multi-step simplification with careful organization.
Teaching tips:
• Keep brackets until you finish applying powers.
• Watch negatives: odd powers keep the negative, even powers make it positive.
• Simplify step-by-step to avoid mistakes.

Worked Example (Proper Exponent Formatting)

Example: x³ × x⁵ = x⁸

Reason: When multiplying the same base, add the exponents (3 + 5 = 8).

Support for EQAO (Richmond Hill)

An EQAO Grade 9 Math Tutor in Richmond Hill can help students:
• Build a consistent step-by-step method for exponent questions
• Catch common mistakes (sign errors, mixing rules, forgetting brackets)
• Practice EQAO-style questions with feedback

If you’re a Grade 11 student in Ontario studying MCR3U (Functions) or a parent seeking professional math tutoring in Richmond Hill, this free worksheet is an essential tool to support your success in math. It includes step-by-step problems, clear layout, and a detailed answer key to help learners practice arithmetic sequences with confidence.

What Are Arithmetic Sequences?

An arithmetic sequence is a list of numbers where the same amount is added (or subtracted) each time to get the next number. This constant amount is called the common difference (d). For example:

5, 8, 11, 14, … has a common difference of 3.

The general term of an arithmetic sequence (also called the nth term) is written using the formula:

tₙ = a + (n – 1)d

Where:

• a = the first term

• d = the common difference

• n = the position of the term

• tₙ = the value of the term at position n

Grade 11 students are expected to:
– Understand this formula
– Solve for unknowns like the number of terms
– Apply sequences to real-world problems and function modeling

What’s Included

– 6 scaffolded questions that increase in difficulty
– Focus on problem-solving, term formula writing, and word problems
– Full answer key with step-by-step explanations
– Available in Word (editable) and PDF (printable) formats
– Aligned to the Ontario MCR3U Grade 11 Functions Curriculum

Who This Is For

This resource is ideal for:
– Students preparing for MCR3U quizzes, unit tests, or the final exam
– Parents supporting their child’s independent math review
– Tutors in Richmond Hill offering one-on-one or small group instruction

Let’s go step by step with solving Algebra 1 equations.

Step 1: Solving One-Step Equations

A one-step equation means you only need one operation (addition, subtraction, multiplication, or division) to solve for the variable.

Example 1: Addition/Subtraction

Solve for x:
x + 5 = 12

Solution:

• Subtract 5 from both sides:
  x = 12 – 5
  x = 7

Example 2: Multiplication/Division

Solve for y:
3y = 15

Solution:

• Divide both sides by 3:
  y = 15 ÷ 3
  y = 5

---

Step 2: Solving Two-Step Equations

A two-step equation means you need two operations to isolate the variable.

Example 1: Two Operations

Solve for x:
2x + 3 = 11

Solution:

1. Subtract 3 from both sides:
   2x = 8
2. Divide both sides by 2:
   x = 4

Example 2: Another Two-Step Equation

Solve for y:
5y – 7 = 18

Solution:

Simple Algebra Worksheet:

1. Add 7 to both sides:
   5y = 25
2. Divide both sides by 5:
   y = 5

“In Grade 9 Ontario Math, students are introduced to foundational concepts that prepare them for higher-level math courses. This worksheet, provided by Khoda Zamani, an OCT-certified teacher, is designed to help students review key topics for their final exam. Khoda Zamani also offers math tutoring and physics tutoring to ensure students have the support they need to succeed.”

Sound needs a medium to travel. The speed of sound needs a medium to carry on their wave.

When the temperature of the medium increases the molecules have more energy as a result molecules move faster so the speed of sound can travel faster.

The speed of sound in air at 0 ˚c is 346 m/s.

so

V=346°c

If air temperature increases by 1°c the speed increase by 0.606

So our formula will be

V=331.4m/s+(0.606m/s/˚c)T

Which T indicates the temperature of its units in Celsius.

Example:

Determine the speed of sound at 45.0˚c

Given:T=45.0˚c

Formula:

V=331.4m/s+(0.606m/s/˚c)T

V=331.4m/s+(0.606m/s/˚c)45      (substitude the T in formula)

V=358.67 m/s
