Question 1009707
 state whether the parabola represented by h(t)=-16t^2+250t opens up or down 
Explain why answer make sense int the context of this problem.
----
Downward because, as x gets larger and larger (positively or negatively)
the -16t^2 term grows more and more negative, thus causing the arms
of the parabola to go more and more negative negative, or DOWN.
