For each pair of function f and g below, find f(g(x)) and g(f(x)). Then determine whether f and g are inverses of each other. Simplify your answers as much as possible. Assume your expressions are defined for all x in the domain of the composition.1. f(x) = 1/3x, x not equal to 0 g(x) = 1/3x, x not equal to 0
What does f(g(x)) = , what does g(f(x)) = , Is f and g inverses of each other?2. f(x)= x + 4
g(x)= x = 4
What does f(g(x)) = , what does g(f(x)) = , Is f and g inverses of each other?
