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? (2 points)

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
