1. Domain/Range Notations Foldable October 7, 2014 Pg. 24-25 in Notes http://mathequalslove.blogspot.com/

2. Warm-Up – pg. 24 What is the domain of a function? What is the range of a function?

3. Title – pg. 25 Domain/Range Notations

4. Essential Question What are the different notations for domain and range?

5. Foldable Fold your paper in half.

6. Foldable Cut 2 lines (making 3 sections) on one half of the paper.

7. Label the front flaps. { Set Notation } Algebraic Notation [ Interval, Notation ) > < = ≠ ≥ ≤

8. Fill in the inside.

9. Inside Set Notation Flap If the graph is discrete: List all of the inputs or outputs inside squiggly brackets. Example: D = { 1, 2, 4, 5, 7 }

10. Fill in the inside.

11. Inside Set Notation Flap If the graph is continuous: Inside squiggly brackets, define a variable and describe it algebraically. Examples: { x | x ≥ 5 } or { y | -5 ≤ y < 3 }

12. Fill in the inside.

13. Inside Algebraic Notation Flap Examples: x > 4 and x ≠ 5 y > 5 x ≥ 7 -2 ≤ x < ∞ -∞ < y < ∞

14. Fill in the inside.

15. Inside Algebraic Notation Flap Use equality and inequality symbols and variables to describe the domain and range., ≤, ≥, =, ≠

16. Fill in the inside.

17. Inside Interval Notation Flap Examples: [ 5, 74 ) [ 2, 4 ] ( - ∞, 3 ] ( -100, 4 ] ᴜ [ 17, 23 )

18. Fill in the inside.

19. Inside Interval Notation Flap For each continuous section of the graph, write the starting and ending point separated by a comma. Parentheses: point is not contained in D/R (open circles, ∞, - ∞) Brackets: point is contained in D/R

20. Reflection Which notation(s) are new to you?
