Check for the Functions

Functions are special types of relations that assign each input value to exactly one output value. Use this eighth-grade algebra worksheet to give students practice determining whether given relations are functions. Students will review 12 relations and use their understanding of functions to determine which relations are functions and which relations are not functions. This worksheet is a great way to help students prepare for learning about specific types of functions, such as linear functions. For more practice, students can also complete the Is the Relation a Function? worksheet.
