This video tutorial explains how to identify functions in mathematics. It begins by defining a function as a special relationship where each input has a single output. The video introduces the vertical line test as a method to determine if a graph represents a function. It also covers how to identify functions using tables by ensuring each input has only one output. The tutorial concludes with a call to action to engage with more math content.
