Question

the height h of a projectile at any time t after launch is defined by the function h(t) =5t^2+13t + 6

Answer 1

The equation sets the parabola. You can find the parabola vertex as:

then

This means that the maximum height is 11.375 m and a projectilereaches this height at 1.25 seconds.

The projectile initially launched at time t=0, so the initial height is h(0)=2 m
