Well, you have x to the 5th divided by x to the 5th. These are going to grow together. So you can think of them as canceling out, and so you are left with 2 thirds. 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.
