Question

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group of answer choices g(x) = -8x + 9 g(x) = -8x - 9 g(x) = 8x - 9 g(x) = 8x + 9

Answer 1

Given:

The parent function is

`f(x)=8x+9`

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

`g(x)=-f(x)`

Putting
`f(x)=8x+9`, we get

`g(x)=-(8x+9)`

`g(x)=-8x-9`

The function after the reflection over the x-axis is
`g(x)=-8x-9`.

Therefore, the correct option is B.
