R3 = (b) Find the Riemann sum for this same integral using left endpoints and n = 3. L3: (1 point) Book Problem 5 (a) Find the Riemann sum for f(x) = x3, 3 S x S 14, if the partition points are 3, 6, 11, 14 and the sample points are 4, 9, 12. R = (b) Find the Riemann sum if the partition points are 3, 6, 11, 14 and the sample points are the midpoints. M = (1 point) Book Problem 9 9 A table of values of a decreasing function f is shown.
