Question

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

Answer 1

1) x = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground

2) x = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground

3) x = 3; it takes 3 seconds to reach the maximum height and 3 seconds to fall back to the ground

4) x = 3; it takes 3 seconds to reach the maximum height and 6 seconds to fall back to the ground
