I"m stuck on this question in my calculus book, and am wondering how I should approach it. Here is the question
Find a lower and upper bound for the area under the curve of over the interval [4, 7] by computing two different Riemann sums - one at the left endpoint and the other at the right endpoint - and by
dividing your interval into 3 sub-intervals.
Would this just be calculating F(x) and solding F(7) and F(8)?
THanks a lot!
