Transformations of Linear Functions (Multiple Choice)

Understanding Transformations of Linear Functions

Transformations of linear functions are a crucial concept in mathematics, particularly in algebra and calculus. A transformation of a function is a new function that is obtained by applying a specific operation to the original function. In this article, we will explore the transformations of linear functions and provide a multiple-choice question to test your understanding.

What are Transformations of Linear Functions?

Transformations of linear functions involve changing the original function in some way, such as shifting, scaling, or reflecting it. These changes can be represented graphically or algebraically. For example, if we have a linear function $f(x) = 2x + 3$ , we can transform it by shifting it 2 units to the left, resulting in a new function $f(x) = 2(x - 2) + 3$ .

Types of Transformations

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

Shifting: Shifting a function involves moving it horizontally or vertically. For example, if we shift the function $f(x) = 2x + 3$ 2 units to the left, the new function becomes $f(x) = 2(x + 2) + 3$ .
Scaling: Scaling a function involves changing its slope or y-intercept. For example, if we scale the function $f(x) = 2x + 3$ by a factor of 2, the new function becomes $f(x) = 4x + 6$ .
Reflecting: Reflecting a function involves flipping it over a horizontal or vertical line. For example, if we reflect the function $f(x) = 2x + 3$ over the x-axis, the new function becomes $f(x) = -2x - 3$ .

Multiple Choice Question

Given that $h(x)$ is a transformation of $g(x)$ , which table shows the values of these functions?

x	0	1	3
g(x)	0	4	-7

x	0	1	3
h(x)	3	7	-1

x	0	1	3
h(x)	0	4	-7

x	0	1	3
h(x)	3	7	1

x	0	1	3
h(x)	-3	-7	1

Answer

The correct answer is B)

x	0	1	3
h(x)	0	4	-7

Explanation

To determine the correct answer, we need to analyze the transformation of the function $g(x)$ . Since $h(x)$ is a transformation of $g(x)$ , we can assume that the transformation is a shift of 3 units to the right. Therefore, the values of $h(x)$ will be the same as the values of $g(x)$ , but shifted 3 units to the right.

Conclusion

Transformations of linear functions are an essential concept in mathematics, and understanding them is crucial for solving problems in algebra and calculus. By analyzing the types of transformations and applying them to linear functions, we can determine the correct answer to the multiple-choice question.
