Question 309222
<font face="Garamond" size="+2">


{{{drawing(
500, 500, -5, 5, -10, 100,
grid(1),
graph(
500, 500, -5, 5, -10, 100,
-16x^2+80))}}}


Anything to the left of the y-axis doesn't make any sense in the physical world because negative time doesn't make sense.  Anything below the x-axis doesn't make any sense unless you have some little elves frantically digging a hole for the rock to fall into.


So the domain is 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0\ \leq\ t\ \leq\ \sqrt{5}]


And the range is


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0\ \leq\ h(t)\ \leq\ 80]
