So my question to you, so there's a couple of things. If I were to just evaluate the function g of 2, well, you look at this definition. Okay, when x equals 2, I use this situation right over here, and it tells me it's going to be equal to 1. Let me ask a more interesting question, or perhaps a more interesting question. What is the limit as x approaches 2 of g of x? Once again, fancy notation, but it's asking something pretty, pretty, pretty simple. It's saying as x gets closer and closer to 2, as you get closer and closer, and this isn't a rigorous definition, we'll do that in future videos.
