Caculus help please
(a) Estimate the area under the graph of f(x) = 1 + x^2 from x = -1 to x = 2 using three rectangles and right endpoints. Then improve your estimate by using six rectangles. Sketch the curve and the approximating rectangles.
(c) Repeat part (a) using midpoints

I understand how to do part a. I also understand how to estimate the area.
But can someone help me how to graph it with midpoints (part c)
