f(x)=x^{b}+3, g(x)=a x+c

. If

(g(f(x)))^{-1}=\left(\frac{x-7}{2}\right)^{\frac{1}{3}}

, then

f o g(a c)+g o f(b)

is:

View answer and explanation

Correct option: A

189

Option A (189) is correct because after finding the values of a, b, and c, we can calculate f o g(ac) + g o f(b) which equals 189.
