And I want to think about the limit of f of x as x approaches positive infinity and the limit of f of x as x approaches negative infinity. So let's think about what these are going to be. Well, once again, and I'm not doing this in an ultra rigorous way, but more in an intuitive way, is to think about what this function approximately equals as we get larger and larger and larger x's. This is the case if we're getting very positive x's, very positive infinity direction, or very negative. It's still the absolute value of those x's that are very, very, very large as we approach positive infinity or negative infinity. Well, in the numerator we only have one term. We have this x term.
