You are given four points in the plane A = (-3,-6), B = (0,5), C = (3,-2), and D = (6,7). The graph of the function f(x) consists of the three line segment AB, BC, and CD. Find the integral http://webwork.math.uwyo.edu/webwork...8c55b37701.png by interpreting the integral in terms of the sums and/or differences of areas of elementary figures.

I drew this out and tried to figure out how to draw the shapes but I think I keep messing up my picture.

Thanks to anyone who can help!
