for the first one, using the LRS, you're using the left endpoint of each subinterval: x=-2, -1, 0, 1. the height of the rectangles at each of those left endpoints is f(-2), f(-1), f(0), f(1) So the LRS approximation with n=4 for f(x)=2x^2 is LRS = [ f(-2) + f(-1) + f(0) + f(1) ]*1 basically you do the same thing with the second function but the width of each of your subintervals will now be 2...
