It is a continuous function. So if you're trying to imagine continuous functions, one way to think about it is, if we're continuous over an interval, we take the value of the function at one point of the interval, and if it's continuous, we need to be able to get to the value of the function at the other point of the interval without picking up our pencil. So I can do all sorts of things, and it still has to be a function, so I can't do something like that, but as long as I don't pick up my pencil, this is a continuous function. So there you go. Somehow the graph, I had to pick up my pencil if I had to do something like this, so I got to pick up my pencil and do something like that, well, that's not continuous anymore. If I had to do something like this, and oops, pick up my pencil, not continuous anymore. If I had to do something like, whoop, okay, pick up my pencil, not continuous anymore.
