All right, we've got a question here that gives us the graph of f, and we're asked to calculate which one, or determine which one of these other graphs are the anti -derivatives of a.
00:12
We're just looking at this.
00:13
We can see that it's more than likely going to be this one here.
00:19
This b, and we know that because the graph of the antiderivative is going to be decreasing over the same.
00:37
Okay, basically, you know that if we have an interval from here to here, that this, that the antiderivative of this, for example, point, some point would be decreasing in that same interval.
01:19
So hypothetically, if we had a point, let's say here at a, call that point a, then we can see that point a, then we can see that the interval a to infinity, f has a positive value.
01:50
So the graph with the, the graph of the antiderivor of that is increasing over 8 to infinity...
