Melissa launches a rocket from a 33-meter-tall platform. The height, h, of the rocket, in meters, can be modeled by the given graph. y h(a) 35 30 h(b) 25 (1, 23) : 20 15 10 3. a 4 Melissa knows that h(1) = 23 and h(a) = 34.25 meters. %3D What is a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds? Explain your reasoning.
