For this case we must find the inverse of the following function:
For this, we follow the steps below:
We change f (x) to y:
We exchange the variables:
We solve for y:
We divide between 8 on both sides of the equation:
We raise both sides of the equation to the square to remove the root:
So, the inverse is:

The correct answer is:
[B]: "
" .
__________________________________________________________Consider choice [A]: ;
=
;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
