Consider the function f(x) = x 2 + 3. 3 In this problem you will calculate o 2 + 3) dx by using the definition b n f(x) dx = lim f(x;) Ax i=1 The summation inside the brackets is R, 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) = x 2 + 3 on the interval [0, 3] and write your answer as a function of n without any summation signs.\f7 g(x) dx =
