Chapter 2 Polynomial and Rational Functions. University of Houston, department of Mathematics. 172. Degree of a Polynomial: Example. In speaking one might say a function approaches a certain value as x increases, decreases, or approaches a certain value. To mathematically say "approaches an arrow is used. For example, to say that the function f ( x ) increases without bound as x increases without bound, one would write f ( x )Ü as x Ü.
Or to say the function f decreases without bound as x approaches 0, you would write f ( x )Ü - as x Ü 0. Rational functions often have what are called asymptotes.

Any rational function r ( x ), where q ( x ) is not the zero polynomial.
This Precalculus review (Calculus preview) lesson explains how to find the horizontal (or slant) asymptotes when graphing rational functions. Going on and show you how you can do it in your head. It ll be easy! Given some polynomial guy.
