Use f(x) and g(x) to find each composition. Identify its domain. (Use a calculator if necessary to find the domain.) (a) (fog)(x) (b) (gof(x) (c) (fof)(x) f(x) = x. g(x)=1-x (a) (fog)(x)=1-x (Simplify your answer.) The domain of (fog)(x) is (-co.1). (Type your answer in interval notation.) (b) (gof)(x)=(Simplify your answer.)
