Question

Hi I need help with this question please and thank you

Answer 1

The first thing we need to remember is that a reflection of a function f(x) across the x-axis can be expressed with the equation:

$-f(x)$

Thus, if

$f(x)=x^2$

And g(x) represents the reflection of this function across the x-axis, we could write:

$g(x)=-f(x)$

Which is:

$g(x)=-x^2$
