Consider the function f(x) = - +7. 4 In this problem you will calculate x2 + 7) dx by using the definition b. f(x) dx = lim E 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 R, for f(x) = - +7 on the interval [0, 4] and write your answer as a function of n without any 4 summation signs. R, lim R, = n-00
