A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?

t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
t = 3; it takes 3 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 3; it takes 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.

In order to find the axis of symmetry, you need to set the equation up for graphing in the form
(x−h)2=y−k
