$2 Consider the function f(:r) = 7? + 4. 2 2 In this problem you will calculate / (i z? + 4) dx by using the denition 0 The summation inside the brackets is Rn which is the Riemann sum where the sample points are chosen to be the righthand endpoints of each subinterval. 2 Calculate RH for f (m) = 7% + 4 on the interval [0, 2] and write your answer as a function ofn without any summation signs.
