Let and Compute the Riemann Sum of F Over

Let and compute the Riemann sum of f over the interval [2, 4] , using Two subintervals of equal length (n = 2) .
Five subintervals of equal length (n = 5) .
Ten subintervals of equal length (n = 10) .
In each case, choose the representative points to be the right end points of the subintervals.
