I have a TI-83 graphing calculator and I need to graph the following function:
s(t) = -16t^2 + 80t + 7
I have no idea how to graph this on the graphing calculator. Any help at all would be greatly appreciated
Can you tell me what's in "window" ?
And are you sure you're in the right mode for graphing ? (there is parametric, polar, etc...)
Have you ever saved x as a constant ? I mean sometimes it occurs that in programs you need to give a value to x, and that it has kept it in memory...
