Question

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?

Answer 1

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

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

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

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

Answer 2

is that -16t^2?

Answer 3

On a parabola, the line of symmetry is the line that is passing through the vertex.
