Given F(x) = $x ^ { 3 }$ - 1 on the Interval 1 ≤ X ≤ 5

Short Answer

Given f(x) = $x ^ { 3 }$ - 1 on the interval 1 ≤ x ≤ 5 and with n = 4, compute the Riemann sum (a) using the left endpoints; (b) using the right endpoints; and (c) using the midpoints of the subintervals. Enter your answer as just a, b, c all integers separated by commas.
Enter the numbers in the order that answers (a), (b), (c) but do not label.
