Question

consider the function f defined by f(x) = 4x-12, x ER. FindL f(2) and (f(0)

Answer 1

Given the function f(x) as follows:

$f\mleft(x\mright)=4x-12$

We will Find: f(-2) and f(0)

So, we will substitute x = -2, and 0 into the given function.

$\begin{gathered} f(-2)=4(-2)-12=-8-12=-20 \\ f(0)=4(0)-12=0-12=-12 \end{gathered}$

So, the answer will be:

$\begin{gathered} f(-2)=-20 \\ f(0)=-12 \end{gathered}$
