Answer:
4
Step-by-step explanation:
there are two ways to find the answer
the easiest one (based on me)
(g o f)(6) = g (f(6))
so first find f(6) and take the result and put in g(x)
f(6) = -6 + 8 = 2
g(2) = 2² = 4
the normal way
(g o f)(x) = g(f(x)) = (f(x))² = (-x + 8)²
(g o f)(x) = x² - 16x + 64
(g o f)(6) = 6² - 16(6) + 64 = -60 + 64 = 4
