  2. 6. A set of ordered pairs that relate inputs to outputs.
  3. 7. A mathematical rule that assigns each input value to exactly one output value.
  4. 9. A property of a relation in which if (a,b) is in the relation, then (b,a) is also in the relation.
  5. 10. A property of a relation in which every element is related to itself.
  6. 14. A function that "undoes" the effects of another function, switching the inputs and outputs.

  8. 16. The set of all possible output values for a function or relation.
