*6. Set up (but do not compute) the integrals that would represent the area of the region bounded between the two curves y = r and y = x + x. Set the two functions equal to each other to determine the limits of integration. Use a graphing software or calculator to see a picture of the situation. Note that the upper and lower function will change along the interval! Note: I am just having you set up and not compute the integrals because you should notice that the limits of integration are not particularly nice for this question!
