Answer:
D. -4
Step-by-step explanation:
We have the following function:
[tex]f(x)=4x-12[/tex]
and we are asked to find the value of the function [tex]f(x)[/tex] when the variable [tex]x[/tex] is equal to 2: [tex]f(2)[/tex].
This means that we must substitute the value of [tex]x = 2[/tex] wherever there is an [tex]x[/tex] in the function:
[tex]f(2)=4(2)-12[/tex]
[tex]f(2)=8-12[/tex]
[tex]f(2)=-4[/tex]
The answer is D. -4
