So for this problem, we want to use our graph in order to allow us to calculate the riemensum using left -hand endpoints and eight sub -in intervals.
00:09
So we can see that since our graph goes from 0 through 8, that means that we're essentially just going to multiply our delta x, which is going to be 1, by each of our heights.
00:21
So essentially, we can just add the height at each interval, which will just be each positive integer, 1, or excuse me, 0 through 7, because we're using left endpoints.
00:32
So we can see that at the point zero, we have a y coordinate of three, and we're adding this to, from the x -cordinate of one, we have y -coordinate of two, x -coordinate of two, we have a y -cordid of one, and so forth...
