Form 1: Identifying Functions from Input-Output Tables

Learn how to determine whether a relation represents a function by analyzing input-output tables. Practice checking if each input is paired with exactly one output.

Questions

  1. MultiChoice

    Does the table {(1,2), (2,4), (3,6), (4,8)} represent a function?

  2. MultiChoice

    Does the table {(2,3), (2,5), (4,7), (6,9)} represent a function?

  3. MultiChoice

    Does the table {(-1,5), (0,5), (1,5), (2,5)} represent a function?

  4. MultiChoice

    Is the relation {(1,8), (3,10), (3,12), (4,14)} a function?

  5. MultiChoice
