In this problem you will calculate the area between f(x) - x2 and the x-axis over the interval [2, 11] using a limit of right-endpoint Riemann sums: Area = lim Express the following quantities in terms of n, the number of rectangles in the Riemann sum, and k, the index for the rectangles in the Riemann sum. a. We start by subdividing [2, 11] into n equal width subintervals [x0, x1], [x1, x2], . .., [*n-1, n] each of width Ax. Express the width of each subinterval Ax in terms of the number of subintervals n. Ax = b. Find the right endpoints 21, X2, 3 of the first, second, and third subintervals [xo, x1], [x1, 22], [x2,
