For each pair of functionsfand g below, findf(g(x)) and Then, determine whetherfand g are inverses of each other. SimMy your answers as much as possible. (Assume that your expressions are defined for all x in the domain of the composition. You do not have to indicate the domain.) 4 (a)f(x)=x+3 (b)f(x)=;,xso 4 g(x)=x-3 g(x)=-;,x#0 f(g(x))= [I f(g(x))= El g(f(x))= U g(f(x))= I] Ofand g are inverses of each other Ofand g are inverses of each other Ofand g are not inverses of each other Ofand g are not inverses of each oth
