Question Details:

Do the following. (Round your answers to four decimal places.)

(a) Estimate the area under the graph of f(x) = 8 + 2x2 from x = -1 to x = 2 using three rectangles and right end-points.

R3 = 1

Improve your estimate by using six rectangles.

R6 = 2

(b) Repeat part (a) using left endpoints.

L3 = 3

L6 = 4

(c) Repeat part (a) using midpoints.

M3 = 5

M6 = 6
