Denzel is playing golf. He hits a shot off the tee box that has a height modeled by the function h(t) = -16t^2+64t,
where h(t) is the height of the ball, in feet, and t is the
time, in seconds, it has been in the air.

Part A: Which property of the quadratic will give Denzel information about the time it takes for the ball to reach its maximum height?
• maximum
• axis of symmetry
• y-intercept
• zero

Part B: Select all the expressions that will reveal that property.

• -16 (0)^2 + 64 (0)
• -16t (t-4)
• -16 (t-2)^2 + 64
• -16 (-2)^2 + 64 (-2)
• -64/-2 (16)
• 64/2 (16)
• -64/-2 (32)
