Question 884899
<font face="Times New Roman" size="+2">


a) Substitute 0 for t and solve for h


b) Set the function equal to zero and solve for the positive root


c) Set the function equal to 40 and solve for both roots


d) Set the function equal to 80 and solve for both roots (hint: if the roots are complex, the ball never gets that high)


e) The *[tex \Large x] coordinate of the vertex of *[tex \Large ax^2\ +\ bx\ +\ c] is given by *[tex \Large x_v\ =\ -\frac{b}{2a}].  Use this fact to calculate *[tex \Large t_{max}]


f) Evaluate the function at *[tex \Large t_{max}]

My calculator said it, I believe it, that settles it
