Given the function f(x) as follows:
[tex]f\mleft(x\mright)=4x-12[/tex]We will Find: f(-2) and f(0)
So, we will substitute x = -2, and 0 into the given function.
[tex]\begin{gathered} f(-2)=4(-2)-12=-8-12=-20 \\ f(0)=4(0)-12=0-12=-12 \end{gathered}[/tex]So, the answer will be:
[tex]\begin{gathered} f(-2)=-20 \\ f(0)=-12 \end{gathered}[/tex]
