Let's say the, so let me put a check mark here. That is continuous. Let's think about the interval from negative two to positive one, the open interval. So this is interesting, because the function at negative two is up here, and so if you really wanted to start at negative two, you would have to start here, and then jump immediately down as soon as you get slightly larger than negative two, and then keep going, but this is an open interval, so we're not actually concerned with what exactly happens at negative two. We're concerned what happens when we are all the numbers larger than negative two, so we would actually start right over here, and then we would go to one, and once again, based on the intuitive, I didn't have to pick up my pen idea, this function would be continuous over this interval. So what's an example of an interval where the function would not be continuous? Well, think about the interval from, well, this is a pretty straightforward one, the open interval from three to five.
