The figure below shows the graph of y=e (possibly not to scale), with a division of the interval 0, 4 into eight equal sub-intervats 4. Let R. be the Riemann sum from taking the height of our rectangles from the right-most point of each sub-interval. Then which sum below gives R&? Select one: O ae"(0.5) + (0.5) + e'(0.5) +el (0.5) +e2(0.5) + e(0.5) +e (0.5) +e (0.5) b. 0(0.5) + (0.5)(0.5) + 1(0.5) + 1.5(0.5) + 2(0.5) ++ 2.5(0.5) + 3(0.5) +3.5(0.5) c.
