Finding Asymptotes and Holes of Rational Functions

Finding Asymptotes and Holes of Rational Functions 640 480 joshua
Here we will be looking at some defining features of rational functions: asymptotes and holes. We will begin by defining rational functions,. We will then proceed to uncover how to identify different types of asymptotes and how to distinguish them from holes. In each case, we will use example functions to visualize the effects and representations of these features. read more
