For to figure out what the limit is going to be, we should think about, well what's the limit as we approach from the left? What's the limit as we approach from the right? And do those exist? And if they do exist, are they the same thing? And if they are the same thing, well then we have a well-defined limit. So let's do that. Let's first think about the limit, the limit of f of x as we approach two from the left, from values lower than two.
