  2. Group 1

  3. Group 2

  4. Group 1

  5. Group 2

  6. Vocabulary • Relation – Set of ordered pairs • Function – A relation in which each element of the domain is paired with exactly one element of the range. • Function Notation – f(x) • Domain – Set of Abscissas • Range – Set of Ordinates

  7. State the domain and range of the relation

  8. State the domain and range of the relation

  9. What is the domain and range of the relation{(-3,0),(4,-2),(2,-6)} • Domain – {-3,2,4} • Range – {-6,-2,0} • Yes it is a function

  10. What is the domain and range of the relation{(4,-2),(4,2),(9,-3),(-9,3)} • Domain – {-9,4,9} • Range – {-3,-2,2,3} • No it is not a function

  11. State the domain of the function

  12. State the domain of the function

  13. Evaluate the function
