2. Twofunctions are given as f(x ) = (x+5) and 9 ( x ) = > 2+7x +10 a. Determine h(x) = (* )(x) in simplest form. b. State the domain and range of h(x). 3. a. If f = {(1, 4), (2, 7), (3, 1) }, determine (f . f)(3) and explain. b. If g(x) = Vx and h(x) = x2, determine (g . h)(x) and (h . g)(x). [Hint: (g . h)(x) # (h . g)(x)] c. Determine the domain and range of (g . h)(x) and (h . g)(x)
