Evaluating Limits Numerically (tables), Algebraically, and from Graphs

In this example problem, we are trying to find a limit to a rational function we look at how this is accomplished by using a table, then algebraically by factoring and reducing to lowest terms, finally how the graph would look like with a removable discontinuity. This video contains examples that are from Business Calculus, 1st ed, by Calaway, Hoffman, Lippman. from the Open Course Library, remixed from Dale Hoffman's Contemporary Calculus text. It was extended by David Lippman to add several additional topics. The text is licensed under the Creative Commons Attribution license. http://creativecommons.org/licenses/by/3.0/us/
