Question

f(x) = square root of x, g(x) = x+9

Given functions f and g find (a) (f g)(x) and its domain, and (b) (g f)(x) and its domain f(x) = Squareroot x, g(x) = x + 9 (a) (f g)(x) = (Simplify your answer Type an exact answer, using radicals as needed) The domain of f g is . (Type your answer in interval notation Use integers or fractions for any numbers in the expression) (b) (g f)(x) = (Simplify your answer Type an exact answers using radicals as needed) The domain of g f is (Type your answer in interval notation Use integers or fractions for any numbers in the expression)
