Hmm you would use a Riemann sum or integral but I vaguely remember there is another way.
how would i find the area of everything under that curve???
the drawing is actually wrong but, its supposed to be part of the curve is over a 6 by 6 square (if you connect the dots), umm..just pretend where the curve ends, it is at (6,0) and it is all contained inside from (0,0) to (6,0)
