When you are asked to find the area between two curves, you can start by sketching the graph, which will allow you to better understand the shape of the area of the region needed. Show your work.

Once you have the graph drawn, imagine breaking the area between the curves into a lot of very thin rectangles, each of width "dx". For any given x, what is the height of the rectangle (in terms of "x")?

Thanks for that both of you guys, I understand how to do it now :). Sorry I didn't thank you earlier, I was having trouble with my internet.
