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)= -16x^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 the height. Then find how long the ring is in the air.
y= -x^2 + 6x - 4( i will award with medal)
