b. f(x)= 5x-11 and g(x) = x+11/ 5
c. f(x)= 2+ 3 square root x and g(x)= 2-x^3
d. f(x)= 7/x - 9 and g(x) =x+9/7

Answer 2

Do you know how to find inverses? We can go over one if you want. Any answer choice you wanna try out?

Answer 3

In general, \(\color{#000000}{ \displaystyle f^{-1}(x)=g(x) }\) iff \(\color{#000000}{ \displaystyle f\left[g(x)\right]=g\left[f(x)\right]= x }\).
