In this problem you will calculate the area between f(x) = 9x* and the x-axis over the interval [0, 2] using a limit of right-endpoint Riemann sums: Area = lim 1 100 * 1 Express the following quantities in terms of n, the number of rectangles in the Riemann sum, and &, the index for the rectangles in the Riemann sum. a. We start by subdividing [0, 2] into n equal width subintervals [co, $1], [:1, 2], ..., [In 1, In] each of width Ac. Express the width of each subinterval Ax in terms of the number of subintervals n. Ax b. Find the right endpoints $1, 22, 23 of the first, second, and third subintervals [20, 21], [21, 22], [
