Question

Find (gºf)(3)
f(x) = 3x - 2
g(x)= x^2
a. 1
b.-8
C. 49
d. 52​

Answer 1

C. 49

Explanation:

In order to find the value of (gºf)(3) consider that:

(gºf)(3) = g(f(3))

By using the given expressions for g(x) and f(x) and by using x = 3, we obtain:

f(3) = 3(3) - 2 = 9 - 2 = 7

g(f(3)) = g(7) = 7^2 = 49

Hence, the answer is C. 49
