Actually, let me draw a dotted line at the asymptote. That is y is equal to three, and so you see the function's getting closer and closer as x approaches infinity. But that's not the only function that could do that. As I keep saying, there's an infinite number of functions that could do that. You could have this somewhat wild function that involves natural logs. That too, as x approaches infinity, it is getting closer and closer to three. It might be getting closer to three at a slightly slower rate than the one in green, but we're talking about infinity.
