Suppose you stand in a hole and use a sling to launch a stone straight up. The stone starts with a velocity of 53 feet per second. It leaves
the sling 29 feet below ground level.
Write height (y feet) as a function of time (x seconds)

Read the following question, then decide which strategy you will use.
Plug in x to find y
Plug in y to find x

and then 'plug in
What is the maximum height that the stone will reach? (nearest
hundredth)
