Question

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the 12-foot
fence into the court. The height of the ball, h, and time t seconds is given by the equation
h(t) = -16t
2
+ 18t + 5. Will she make it over the fence?

Answer 1

the equation is -16t^2+18t+5

Answer 2

the maximum will occur at the value t = -b / 2a where a = -16 and b = 18

calculate the t value, then plug that t value into the function to determine the maximum height of the ball
