. During a volleyball game, Christine dove to save a ball. The function h(t)=-4.9t^2+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)=I-4.9t^2+8.5t-2.23I
represents the distance between the bottom of the ball and the top
of the net after t seconds. Explain this function.

d(t) = |h(t)-2.23|
recall that |x-y| is the distance between x and y
