G of 2.99 is getting even closer to two. G of 2.999999 would be even closer to, so it looks like this thing right over here is approaching two. So both of these limits, the limit from the right and the limit from the left, exist. The limit of g of x as x approaches three exists. So these are the one-sided limit. This is the actual limit. Now in order for this to exist, both the right and left-handed limits need to exist, and they need to approach the same value.
