Let *f*(*x*) = *x*^{2} 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).

Step 1

Find the intervals first.

Step 2

Now, we evaluate the function at the left endpoints.

Finally, sum up the above values and multiply by delta x=1

1(49+64)=113

Answer(a): 113

Step 3

b) Find the interv...
