Just giving a number as an answer will result in no credit. Evaluate the Riemann sum with 8 subintervals of equal length using the right endpoints of each subinterval in order to approximate the integral: 3 (x2 + 1)dx. So, you will be using the Right Hand Rule formula, with n = 8. This question does not require you to take any limit
