In this situation, they aren't. As we approach two from values below two, the function seems to be approaching five, and as we approach two from values above two, the function seems to be approaching one. So in this case, the limit, let me write this down, the limit of f of x as x approaches two from the negative direction does not equal the limit of f of x as x approaches two from the positive direction. And since this is the case that they're not equal, the limit does not exist. The limit as x approaches two in general of f of x, or the limit of f of x as x approaches two does not exist. In order for it to have existed, these two things would have had to been equal to each other. For example, if someone were to say, what is the limit of f of x as x approaches four, well, then we could think about the two one-sided limits, the one-sided limit from below and the one-sided limit from above.
