What to Focus On

  • Order matters in ordered pairs.
  • Cartesian product means all possible ordered pairs from two sets.
  • If either set is empty, the product is empty.
  • A relation is a subset of a cartesian product.
  • Domain = set of first elements.
  • Range = set of second elements.
  • A function is a relation with exactly one image for each domain element.
  • Domain of a function must be the whole set A.
  • A function is written as f: A → B.

Common Mistakes to Avoid

A Cartesian product is the same as a normal pair of sets, so A × B equals B × A.

If one set is empty, the Cartesian product is still formed using the other set.

The number of elements in A × B is n(A) + n(B).
