This is topic 2 in my AP Calculus curriculum. This PowerPoint guides students through how to calculate a limit of a function. Students are asked to use a graphing calculator to find the limit. However, I do include a section on how to determine the limit from a graph and table without the graphing calculator. You may either have students go through the PowerPoint on their own or you may do it as a whole class. It is best used with the corresponding notes that I have created for it.
