Chapter 2.5, Problem 93AYU

To determine

To explain: the change the value of $a$ from 1 to $-1$ .

Explanation of Solution

Suppose that $g\left(x\right)=f\left(x\right)$

If the values of $a$ changes from 1 to $-1$ , then $g\left(x\right)=f\left(-x\right)$

Since $y=f\left(x\right)$ and $y=f\left(-x\right)$ are equidistance from the $y$ axis, therefore $g\left(x\right)=f\left(-x\right)$ is the reflection of the graph $g\left(x\right)=f\left(x\right)$ .
