So here, I would say, at least from what we can tell from the graph, it looks like the limit of f of x as x approaches four is three, even though the function itself is not defined there. Now let's think about the limit as x approaches two. So this is interesting. The function is defined there. F of two is two. But see, when we approach from the left-hand side, it looks like our function is approaching the value of two. But when we approach from the right-hand side, when we approach x equals two from the right-hand side, our function is getting closer and closer to five.
