We're getting closer and closer and closer to three. And you could also think about what happens as x approaches negative infinity. And here you're getting closer and closer and closer to three from below. Now one thing that's interesting about horizontal asymptotes is you might see that the function actually can cross a horizontal asymptote. It's crossing this horizontal asymptote in this area in between. And even as we approach infinity or negative infinity, you can oscillate around that horizontal asymptote. Let me set this up.
