First find the intersections between the two curves, they are the limits of integration. They can be found readily as x=±2. Next, we check that the curves do not cross the axis y=-1 between the limits of integration. Otherwise the limits of integration must change. Now ...

Ok so let me start over. System of equation can be solved by graphing, substitution or elmination method. I only have to choose one method and I was trying the elimination method is that how my problem seems to be?
