So we're given this table for the values of f of x.
00:05
We have x is 1, 2, 3, 4, 5, and then we have that the values here are 9, 2, 2, negative 3, negative 3.
00:34
So then what we have is that with three equal subintervals, this actually goes to 7, and then here it's going to be 2, 2, negative 7, negative 3, negative 3, negative 6.
00:54
So if we're going from 1 to 7, our delta x is going to be b minus a over n, which is 7 minus 1 over, we have six, three equal subintervals.
01:06
So that's going to be a delta x of 2...
