What to Focus On

  • Cartesian product forms ordered pairs or ordered triplets.
  • Order matters in ordered pairs and triplets.
  • A × B is generally not equal to B × A.
  • A relation is a subset of a Cartesian product.
  • Domain comes from first elements; range comes from second elements.
  • Range is always inside the co-domain.
  • Every function is a relation.
  • Each element of the domain must have exactly one image.
  • A missing image means the relation is not a function.

Common Mistakes to Avoid

A function and a relation are the same thing.

If one element of the domain has two images, the relation can still be a function.

The domain of a relation from A to B is always A.
