Determining Functions on Graphs

The video tutorial explains how to determine if a line on a graph represents a function by mapping inputs to outputs. It covers the concept of ordered pairs, the definition of a function, and the use of the vertical line test to identify functions. The tutorial also addresses common misconceptions about horizontal line tests and analyzes different graph types, such as circles and lines, to determine their function properties.
