How do you solve this math problem?
h= 8t^2+40t
then it says:
when t=0 and when t= 5
there are 2 questions that i have to answer:
1.) find the value of h
2.) graph this equation
 i don't know if i did the problem right but when i answered #1 i got h=0,
 and when i answered #2 the 8 and y coordinates that i was supossed to point were too high, like (1,32), (2,48,), (3, 48), etc. but our graph only goes up to 1520, so either i did it wrong, or I need to know how to change the interval values on the a ti84 graphing calculator
~ so just show me how to solve each problem, and if you have to change the intervals tell me what buttons to press! thanks so much!

1. is correct
2. not sure, sorry
