These are the dominant terms. We're going to get it equaling 2 thirds. Once again, you see that in the graph here. We have a horizontal asymptote at y is equal to 2 thirds. Whether we take the limit of f of x as x approaches infinity, we get 2 thirds. And the limit of f of x as x approaches negative infinity is 2 thirds. In general, whenever you do this, you just have to think about what terms are going to dominate the rest and focus on those.
