To answer this question, first you need to find the (g°f) function. It will be found by inserting the f (x) into g (x). It should be:

g (x) = x^4

(g°f) (x) = (2x+8) ^4

(g°f) (-3) = (2*-3+8) ^4

(g°f) (-3) = (8-6) ^4 = 2^4 = 16

G (f (x)) = (2x+8) ^4=>g (f (-3)) = (2 (-3) + 8) ^4 = (-6+8) ^4 = (+2) ^4=16
