Question

In the problem I'm looking at, they want the area between the curves y=(2x+16)/3, y=-2x+8, and y=x2. The problem I encountered was after they set up the integrals and began solving for the area. Obviously they break up the integrals. The first on the region [-2,1] and the second on the region [1,2]. I see no problem with this; however when they begin solving, the second region switches to [0,2] and those are the numbers they plug into the equation. This seems incorrect to me, but am I wrong?
