Question

Choose the correct answer.
-
Let f(x) = x - 4 and g(x) = x2. Find (gof)(-3).
A.1
B.12
C.49
D.-7

Answer 1

Answer would be C.49

Explanation:
To rewrite (gof)(-3)

(g(f(-3)) and solve
F(-3)=(-3)-4

F(-3)=-7 then substitute -7 in (f(-3)) in (g(f(-3))
So,

g(-7) then solve for g(-7)

(-7)^2= 49
