Question

A volleyball is served by a 6-foot player at an initial upward velocity of 33 feet per second. The situation is modeled by the equation h=−16t2+33t+6 h representing the height in feet and t representing the time in seconds. Using this equation, define the domain of the ball when it reaches its maximum height.(1 point)

The maximum occurs at the vertex: t = -b/(2a) = -33/(2·-16) = 33/32 ≈ 1.03 s.
