can someone please show me the detail steps and solution of this problem ? Thanks

Consider the function f(x) = ac- + 9. In this problem you will calculate c 2 3 + 9 da by using the definition f(x) dx = lim The summation inside the brackets is Rn which is the Riemann sum where the sample points are chosen to be the right-hand endpoints of each sub-interval. Calculate Rn for f(x) =- + 9 on the interval [0, 2] and write your answer as a function of n without any summation signs. You will need the summation formulas n 1 + 2 + 3 + . . . +n= i n(n + 1) n- + n 2 2 n 12 + 22 + 32 + ... + n- n(n + 1) (2n + 1) 2n3 + 3n2 + n 6 6 Rn = n- lim Rn =
