A football is kicked toward the goal. The height of the ball is modeled by the function h(t) = -16t2 + 64t 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

t = 2; it takes 2 seconds to reach the maximum height and 2 seconds to fall back to the ground

t = 2; it takes 2 seconds to reach the maximum height and 4 seconds to fall back to the ground

t = 4; it takes 4 seconds to reach the maximum height and 4 seconds to fall back to the ground

t = 4; it takes 4 seconds to reach the maximum height and 8 seconds to fall back to the ground

Answer 2

Answer 3

t is the time right?

Answer 4

therefore when t=4 used in the function the h(t)=0

Answer 5

when t=0 and t=4, the function h(t)=0 then the axis of symmetry is 2 because when t=2 h(t) reaches the maximum height of the ball
