4.2 Riemann Sums: Problem 9 (I pt) Consider the function f(x)+3 In this problem you will calculate +3 dx by using the definition i=1 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 subinterval Calculate Rn for( formulas we learned in class.) +3 on the interval [0, 4 and write your answer as a function of n without any summation signs. (You will need the summation Rn
