# For each pair of functions f and g below, find f(g(x)) and g

For each pair of functions f and g below, find f(g(x)) and g(f(x)). Then, determine whether f and g are inverse of each other.Simplify answers as much possible. Assume that your expressions are defined for all x in the domain of the composition.a) f(x)= x-1/2, g(x)=2x-1, f(g(x))= , g(f(x))=b) f(x)=-3/x, x≠0, g(x)=3/x,x≠0, f(g(x)), g(f(x))
