4. When Greg dives from a platform with an initial upward velocity of 12 ft/s, his height h (in feet) above the water is modeled by the function: h(t) = -16t2+12t+33, where t represents the number of seconds after the jump. (a) How high is the platform? (b) When does Greg reach his maximum height? (c) What is Greg's maximum height?
