Bell Work

1
Bell Work

• Turn in your homework, get your Binder and
  Textbook
• Individually, use your handout yesterday about
  giving Archimedes a bath to determine where on
  the graph on your paper should the labels P, P,
  W, W, D, D should go.
• When you work individually, there should be NO
  TALKING with one another!!!!!!!

2
Linking Graphs to Event Review

• I will create a distance versus time graph and
  you must match the motion

Group Definitions Examples

• Definitions
• Function Rule
• Function
• Domain
• Range
• Relation
• Vertical Line Test

4
Notes

• Dependency
• Y 13X 3
• Y depends on X
• X 5Y 2
• X depends on Y

5

• Dependency (continued)
• Which is dependent and independent
• 5x3 3x 4 3 5y2 4y
• Cant tell which is dep. or indep. Because no
  variable is by itself.

6

• Domain and Range
• (1, 7) , (2 , 12)
• X Y
• Domain 1 , 2
• Range 2, 12
• (-1 , 2) , (3 , 12) , (4 , 15) , (5 , 20)
• Domain -1,3,4,5
• Range 4,12,15,20

7

• Domain and Range (Continued)
• What is the Range when Domain is given
• Y (1/2)X 4 Domain -4 , -1 , 0 ,
  10
• PLUG IN EACH NUMBER AND YOU GET
• Range 2 , 3.5 , 4 , 9

8
Notes

• Relation versus Function
• Simply put, a relation is any set of two numbers,
  like an ordered pair
• Functions have only one y for every x
• only one dep. for every indep.
• only one range for every domain
• If one X has two Ys then it is not a function

9

• IV. Function Test (Do not copy in notes)
• (1 , 3) , (4 , 8) , (-4 , 8) , (2 , 1)

10
Activity

• Freeze Tag (Continued)

Group Work

• What did the baby Porcupine say when it backed
  into a cactus?

Individual Work

• Domain and Range Homework (Numbers 1-10 ODD ONLY)

Odd Only
13
Homework

• Domain and range Homework (s 2-10 even) Do it
  on the same paper as the group and individual
  work and you will turn it all in tomorrow for a
  grade.
