To determine whether a relationship is a function, identifying the input and output values is crucial. If each input value results in just one output value, the relationship is defined as a function. If any input value results in two or more outputs, the relationship is not a function. It is important for students to determine if a relation is a function quiz for better understanding of the function relationship.

Teachers should encourage students to determine if a relation is a...
