So what you could say is the limit of f of x as x approaches infinity, as x gets larger and larger and larger, all of these other terms aren't going to matter that much, and so it's going to approach 2 thirds. Now let's look at the graph and see if that actually makes sense. What we're actually saying is that we have a horizontal asymptote at y is equal to 2 thirds. So let's look at the graph. So right here is the graph. Got it from Wolfram Alpha. We see indeed as x gets larger and larger and larger, f of x seems to be approaching this value that looks right at around 2 thirds.
