Consider the given graph of the function below.
00:02
In here, we first want to find the limit of f of x as x approaches 0, either from the left or from the right.
00:11
So if you look at the graph, as we get closer to 0, either from the left side or from the right side, the value of the function goes to 3.
00:21
So the value of this limit must be 3.
00:26
For part b, you want to find the limit of the same function as x approaches 3, but from the left side.
00:37
So the first thing you have to do is to locate x equals 3, which is over here.
00:44
And then x values left of 3 are those that are close to 3, but smaller than 3.
00:52
So if we get closer to 3 coming from this side, the value of the 1.
00:58
Function approaches 4.
01:01
It can't be 2 because we don't have a graph here.
01:06
So this limit is equal to 4.
01:09
For part c, we're looking for the limit of the same function as x approaches...
