Question 1181410
<font face="Times New Roman" size="+2">


The function is of the form *[tex \Large y(x)\ =\ a(x\,-\,h)^2\ +\ k]


which graphs as a parabola with vertex at *[tex \Large (h,k)] and is convex in a  direction commensurate with the sign on the lead coefficient; positive up and negative down


Given this information, you can determine that the vertex is a maximum, and you can determine the time and the height by inspection if you note that the vertex is the point *[tex \Large \(t_{max},h\(t_{max}\)\)]
