A graph of a function, and we want to find some limits.
00:04
And let's go ahead and tackle this.
00:07
So the first one i'm going to find is the limit as x approaches.
00:15
And i'm going to copy this because a lot of these are the same.
00:17
So it's 4, and then we want f of x equals.
00:21
This is all very similar.
00:33
So the first one is 4 with the negative sign up here, which means from the left, from the negative side.
00:39
So as x approaches, oh, that's a negative 4.
00:43
And that's a negative 4.
00:45
And that's a negative 4.
00:47
And then these two are zeros.
00:48
And there's a few more, but this will make sure i get the right equations there, or the right statements.
00:56
It's actually a 4.
01:00
And then there's one more.
01:04
It's a 6.
01:06
All right.
01:07
So these are what we're going to figure out.
01:08
And so there's some other things we're going to add here.
01:10
So the limit as x approaches negative 4 from the left, this little negative means from the left.
01:15
So negative four is here.
01:16
So as the graph goes closer to negative four from the left, it goes towards negative infinity.
01:23
Now it's negative four with the plus, which means from the right, from the positive side.
01:29
So we approach negative four from the right and it seems to go up to infinity.
01:35
Now this third one is x approaches negative four.
01:40
No plus or minus, which means from the left and the right.
01:43
And they're different, right.
01:44
This goes towards negative infinity...
