Answer:

  (d)  y' = 12x -23

Step-by-step explanation:

The transformation that translates function y = f(x) by h units right and k units up is ...

  y' = f(x -h) +k

__

Your function is ...

  y = 12x

and you want to translate it by (h, k) = (4, 25). That makes it ...

  y' = 12(x -4) +25 = 12x -48 +25

  y' = 12x -23
