What is the definition of function?

• Has inputs and outputs

• Every input has only ONE output

  The situation makes sense

• Inputs have different outputs every time

• x-values and y-values

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range set.

*If the value repeats you only have to list it once*

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

All of the y values or outputs are called what?

• Domain
• Range

• Function
• Not a Function

CCSS.8.F.A.1

• It is a function because each x has only one y.
• It's not a function because an x has multiple y's.
• It's not a function because a y has multiple x's.
• It is a function because each y has only one x.
