f(x) = square root x-3
g(x) = x^2 +3

Use composition to verify whether the functions are inverses of each other. If the functions are inverses, what is f(g(x))?

A) The functions are not inverses of each other.

B) The functions are inverses. f(g(x)) = 1

C) The functions are inverses. f(g(x)) = x^2

D) The functions are inverses. f(g(x)) = x
