What to Focus On

  • Order matters in ordered pairs: (2, 3) ≠ (3, 2)
  • If either set is empty, then X × Y = ∅
  • X × Y ≠ Y × X unless X = Y

  • A relation is any subset of X × Y
  • Domain consists of all x-values that appear in the relation
  • Range consists of all y-values that appear in the relation

  • Each input (x) must have exactly one output (y)
  • Different inputs can have the same output
  • Domain = set of all possible inputs

Common Mistakes to Avoid

Every relation is a function

Domain and range are always the same as the given sets X and Y

If f(x₁) = f(x₂), then x₁ = x₂ for all functions
