Given functions f and g, find (a) (fog)(x) and its domain, and (b) (gof)(x) and its domain. f(x) = vx, g(x) = x + 4 (a) (fog)(x) = ( (Simplify your answer. Type an exact answer using radicals as needed.) The domain of fog is (Type your answer in interval notation. Use integers or fractions for any numbers in the expression.) (b) (gof)(x)=( ) (Simplify your answer. Type an exact answers, using radicals as needed.) The domain of gofis (Type your answer in interval notation. Use integers or fractions for any numbers in the expression.)​
