Evaluating Limits 3: Limits that Approach Infinity or Do Not Exist (Involving Undefined Values of x) 

This video discusses how to evaluate a limit that initially yields an undefined result. After discussing what it means to be undefined, the video discusses how to determine the value of a limit at a value of x that is undefined and how to determine whether it is positive infinity, negative infinity, or the limit does not exist. 3 worked out and explained examples are included, and 4 addition practice questions with solutions are provided at the end.
