A juggler tosses a ring into the air. The height of the ring in feet above
the juggler’s hands can be modeled by the function f (x) = -16 x 2 + 16x, where x is
the time in seconds after the ring is tossed. Find the ring’s maximum height above
the juggler’s hands and the time it takes the ring to reach this height. Then find how
long the ring is in the air.

Question

A juggler tosses a ring into the air. The height of the ring in feet above
the juggler’s hands can be modeled by the function f (x) = -16 x 2 + 16x, where x is
the time in seconds after the ring is tossed. Find the ring’s maximum height above
the juggler’s hands and the time it takes the ring to reach this height. Then find how
long the ring is in the air.

To find the time, what point on the graph would you be looking for? How would you find it?
