-3f(x-4)=x^2

i have no clue what to do with the -3 in front of the f. please explain step by step as to how to do this question
the answer in the back is
-3x^2+24x-48

    The problem probably said:
    if f(x) = x^2 , find -3f(x-4)

    f(x) = x^2
    f(x-4) = (x-4)^2 = x^2 - 8x + 16
    then -3f(x-4) = 3(x^2 - 8x + 16)
    = -3x^2 + 24x - 48
