And if we simplify this, this is going to be equal to the limit as x approaches negative infinity of 1 over 2x. And what's this going to be? Well, if the denominator, even though it's becoming a larger and larger and larger negative number, it becomes 1 over a very, very large negative number, which is going to get us pretty darn close to 0, just as 1 over x as x approaches negative infinity gets us close to 0. So this right over here, the horizontal asymptote in this case is y is equal to 0. And I encourage you to graph it or try it out with numbers to verify that for yourself. The key realization here is to simplify the problem by just thinking about which terms are going to dominate the rest. Now let's think about this one.
