Answer:

D. -6

Explanation:

Hi!!! You have to substitute 2 for f(x) & for the x next to 3!!!

f(x) = 3x- 12

f(2) = 3(2) - 12

= 6 - 12

= 6 -12

= -6

f(2) This means that x is 2, so you can plug in 2 for "x" in the equation


f(x) = 3x - 12

f(2) = 3(2) - 12

f(2) = 6 - 12

f(2) = -6

Your answer is D
