Respuesta :

f(x-4) = 3(x-4)^2 - 5(x - 4) + 4 = 3x^2 - 29x + 72.

1) Because we are given f(x-4), we replace all x values in our given equations with x-4 to get 3(x-4)^2-5(x-4)+4.

2) Simplify: 3(x^2-8x+16)-5x+20+4

                  3x^2-24x+48-5x+24

                  3x^2-29x+72

Answer

D) f(x-4) = 3x^2-29x+72
