Let f(x) = x2 and compute the Riemann sum of f over the interval [7,9], using the following number of subintervals (n). In each case, choose the representative points to be the right endpoints of the subintervals. (Round your answers to two decimal places.)
(a) Use two subintervals of equal length (n = 2).
(b) Use five subintervals of equal length (n = 5).
(c) Use ten subintervals of equal length (n = 10).
Find the intervals first.
Now, we evaluate the function at the left endpoints.
Finally, sum up the above values and multiply by delta x=1
b) Find the interv...
