Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other
Given the functions expressed as:

In order to check whether they are inverses of each other, we need to show that h(g(x)) = g(h(x))
Get the composite function h(g(x))

Get the composite function g(h(x))

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other
