How to determine the limit of a graph from the left and right side

The video tutorial reviews the concept of right and left hand limits, using the function F of X as an example. It explains how to determine the limit as X approaches a specific value from both sides and discusses the notation used. The tutorial highlights that if the left and right hand limits are not equal, the limit does not exist. It also clarifies that the function value at a point may differ from the limit.
