We care about the entire region between the points where they intersect. So let's make sure we get our interval. So to figure out our interval, we just say, well, when does y equal x intersect y equal x squared minus 2x? So we just have to say, when does x, let me do this in a different color. We just have to think about when does x equal x squared minus 2x? Equal x squared minus 2x. When are our two functions equal to each other?
