Find the area between each curve and the x-axis for the given interval:

y=2x^2+x+1 from x=3 to x=6

**drwls**, Thursday, May 15, 2008 at 12:22amThis looks like integral calculus, so why do they call it precalculus?

The area is the definite integral of the function y(x) from 3 to 6.

The definite integral is the change in the indefinite integral going from x=3 to x=6.

The indefinite integral is

(2/3)x^3 +x^2/2 + x

Calculate the value of that function at x=6 and subtract the value at x=3.
