Math Problem Statement

Write a function g whose graph represents a reflection in the y-axis followed by a translation 3 units to the right of the graph of f(x)=|x|

Solution

To create a function g(x)g(x) that represents a reflection in the y-axis followed by a translation 3 units to the right of the graph of f(x)=xf(x) = |x|, we can follow these steps:

1. Reflect the graph in the y-axis:

Reflecting the function f(x)=xf(x) = |x| in the y-axis results in the function f(x)=x=xf(-x) = |-x| = |x|. Since x|x| is an even function, reflecting it over the y-axis does not change its appearance. So after the reflection, the function is still x|x|.

2. Translate the graph 3 units to the right:

To translate the graph 3 units to the right, replace xx in the function with x3x - 3. Thus, the translated function is f(x3)=x3f(x - 3) = |x - 3|.

Final Function:

The final function g(x)g(x) is: g(x)=x3g(x) = |x - 3|

This function represents the graph of f(x)=xf(x) = |x| reflected in the y-axis and then translated 3 units to the right.

  1. How would the graph of f(x)=xf(x) = |x| change if reflected over the x-axis instead?
  2. What would be the equation if the graph was translated 3 units to the left instead?
  3. How does a vertical translation affect the function f(x)=xf(x) = |x|?
  4. Can you describe the transformations needed to shift f(x)=xf(x) = |x| 2 units down and 4 units to the left?
  5. What is the effect of multiplying the function f(x)=xf(x) = |x| by a negative constant?

Tip: When reflecting a function over the y-axis, always replace xx with x-x in the function.
