During a volleyball game, Christine dove to save a ball. The function h(t)=- 4.9ť + 8.5t approximates the height of the ball above the ground in metres, t seconds after it is hit. a. If the net is 2.23 m tall, the function d(t)=|-4.9t + 8.5t – 2.23 represents the distance between the bottom of the ball and the top of the net after t seconds. Explain this function.
