Here, we're given the graph of a function, and we're asked to find the limit as x approaches some value.
00:07
In this case, it's three.
00:09
So when you want to find a limit, what you're going to want to do is start off by finding the x value.
00:15
Here's the x value of three.
00:16
That's the limit value.
00:18
Now, i'm going to move a little bit to one side, say left.
00:21
If i go left, i'm going to go just a little bit.
00:24
Try not to go too far.
00:26
And then find the graph.
00:28
Now, i want to go infinitely close to that x.
00:32
Values of 3 by following the curve.
00:34
Notice, i don't actually have to hit 3.
00:37
I want to get infinitely close to 3.
00:40
And when i do, what happens to the y value? well, as i get infinitely close to 3, the y value is going to get infinitely close to 1...
