Answer :
f(x) = x^2 + 3
g(x) = 3x + 7
(g o f)(x) = g(f(x)) = g(x^2 + 3) = 3(x^2 + 3) + 7 = 3x^2 + 9 + 7 = 3x^2 + 16
(g o f)(7) = 3(7)^2 + 16 = 3(49) + 16 = 147 + 16 = 163
g(x) = 3x + 7
(g o f)(x) = g(f(x)) = g(x^2 + 3) = 3(x^2 + 3) + 7 = 3x^2 + 9 + 7 = 3x^2 + 16
(g o f)(7) = 3(7)^2 + 16 = 3(49) + 16 = 147 + 16 = 163
Answer:
163
Step-by-step explanation:
f(x) = x^2 + 3
g(x) = 3x + 7
(g o f)(7) = 3(7)^2 + 16 = 3(49) + 16 = 147 + 16 = 163
