Parent Function And Transformation Worksheet

Understanding Parent Functions and Transformations

Parent functions are the simplest form of a function, and they can be transformed to create more complex functions. In this blog post, we will explore the concept of parent functions and transformations, and provide a worksheet to help you practice.

What are Parent Functions?

Parent functions are the basic functions that can be transformed to create other functions. They are the simplest form of a function and are used as a starting point for more complex functions. Some common parent functions include:

• Linear functions: f(x) = x
• Quadratic functions: f(x) = x^2
• Cubic functions: f(x) = x^3
• Absolute value functions: f(x) = |x|
• Square root functions: f(x) = √x

Types of Transformations

There are several types of transformations that can be applied to parent functions, including:

• Horizontal Shift: A horizontal shift is a transformation that moves the graph of the function horizontally. For example, if we have a function f(x) = x and we want to shift it 2 units to the right, the new function would be f(x) = x - 2.
• Vertical Shift: A vertical shift is a transformation that moves the graph of the function vertically. For example, if we have a function f(x) = x and we want to shift it 2 units up, the new function would be f(x) = x + 2.
• Horizontal Stretch: A horizontal stretch is a transformation that stretches the graph of the function horizontally. For example, if we have a function f(x) = x and we want to stretch it by a factor of 2, the new function would be f(x) = 2x.
• Vertical Stretch: A vertical stretch is a transformation that stretches the graph of the function vertically. For example, if we have a function f(x) = x and we want to stretch it by a factor of 2, the new function would be f(x) = 2x.
• Reflection: A reflection is a transformation that reflects the graph of the function across the x-axis or y-axis. For example, if we have a function f(x) = x and we want to reflect it across the x-axis, the new function would be f(x) = -x.

Transforming Parent Functions

To transform a parent function, we can apply one or more of the transformations listed above. For example, if we have a parent function f(x) = x^2 and we want to shift it 2 units to the right and stretch it by a factor of 2, the new function would be f(x) = 2(x - 2)^2.

📝 Note: When transforming a parent function, we can apply multiple transformations in any order. However, the order in which we apply the transformations can affect the final result.

Worksheet

Here is a worksheet to help you practice transforming parent functions:

Transformations Worksheet

1. Transform the parent function f(x) = x^2 by shifting it 3 units to the left and stretching it by a factor of 3.
2. Transform the parent function f(x) = |x| by reflecting it across the y-axis and shifting it 2 units up.
3. Transform the parent function f(x) = √x by stretching it by a factor of 2 and shifting it 1 unit to the right.
4. Transform the parent function f(x) = x^3 by reflecting it across the x-axis and shifting it 2 units down.
5. Transform the parent function f(x) = x by stretching it by a factor of 2 and shifting it 1 unit to the left.

Answers

1. f(x) = 3(x + 3)^2
2. f(x) = -|x| + 2
3. f(x) = 2√(x - 1)
4. f(x) = -(x + 2)^3
5. f(x) = 2(x - 1)
