This is a set of 20 task cards with graphs, tables, ordered pairs, and mapping diagrams. For each card, students are asked to determine if the relation is a function or not. The answer includes a brief description why when relations are NOT functions. Students are also asked to find the domain and range of the relations. Domains and ranges for discrete relations are given in set notation on the answer key. There are 3 graphs that are continuous. Those domain and ranges are provided in both interval notation and inequality notation.

The answer key is designed to be printed on the back of the card. (When printing, select flip on the short side to get everything to line up.)

This is a great warm up activity or check your understanding activity where students can pair up and quiz each other. Since answers are provided, their partner can let them know if they are correct.
