find the vertex for the preceding algebraically:
h(t)=-16t^2+8t+8000
& then use the t- intercepts and the vertex to define a reasonable window for a graphing calculator. please help!! & thank you so much

h(t)=-8(2t^2-t-1000)
= -8(2t -45 )(t+22) about...
so t= about 22.5 and -22
I would graph it fom -20 to 20
