    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

    D. - 6

    Step-by-step 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
