Question 1162031
<font face="Times New Roman" size="+2">


The graph of *[tex \Large s(t)] is a parabola opening downward.  The value of the function at the vertex is the maximum height and the value of the independent variable at the vertex is the time relative to the instant of launch for the projectile to reach maximum height.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ ax^2\ +\ bx\ +\ c]


has a vertex at the point


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \(\frac{-b}{2a},\,f\(\frac{-b}{2a}\)\)]


Use the coefficients from your given function to calculate the desired values.

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