    You can use a summation of areas of rectangles under the graph. |dw:1354592872973:dw| Width of each rectangle will be: \[w={{b-a}\over n}\]Where b=right limit=2 a=left limit=-2 n=number of rectangles. Then: \[\sum_{n=1}^{n} w f(a+wn)\] But because the graph goes into the negative you'll need to find the area of -2<=x<=0 and add on the area of 0<=x<=2 to get the total area.
