Question

Find and simplify the expression if

Answer 1

Answer:

$f ( 2 x ) = 4 x ^ 2 - 8$

Step-by-step explanation:

We are given the following expression and we are to simplify the given function:

$f ( x ) = x ^ 2 - 8$

Applying the function $f(2x)$ on $f ( x ) = x ^ 2 - 8$ to get:

$f ( 2 x ) = ( 2 x ) ^ 2 - 8$

$f ( 2 x ) = 4 x ^ 2 - 8$
