Determining Functions from Ordered Pairs

The video tutorial explains how to determine if a set of ordered pairs represents a function. It begins by defining functions and ordered pairs, emphasizing the importance of each input having a unique output. Various examples, such as a fast food menu and test scores, are used to illustrate the concept. The tutorial also discusses scenarios where a relation is not a function, such as when an input has multiple outputs. The lesson concludes with a review of function concepts, highlighting the importance of matching X values to Y values to identify functions.
