What to Focus On

  • A set is a well-defined collection of distinct objects.
  • Roster form lists all elements; set-builder form uses a rule.
  • Standard notations: N, W, Z, Q, R, C.
  • Ordered pairs have a specific order: (a, b) ≠ (b, a).
  • Cartesian product A × B forms all possible ordered pairs.
  • Number of elements in A × B is |A| × |B|.
  • A relation is a subset of A × B.
  • Domain: set of first elements; Range: set of second elements.
  • Void relation has no elements; universal relation has all possible pairs.

Common Mistakes to Avoid

Every relation is a function.

Domain is just all real numbers unless there's a square root.

Range is the same as co-domain.
