Question

A ball is tossed in the air and moves according to the following quadratic function:h(t)=-t^2+6t-7. In the model, h is measured in feet and t is measured in seconds. According to this model, what will be the maximum height of the ball. A) 2ft B)5ft C)1/2ft D)4/3ft

Answer 1

Explanation:

For this dome shaped parabola. max will occur at t = - b/2a

t = - 6 / (2 *-1) = 3 seconds

subbing this value of 't' into the equation results in h = 2 ft
