Determining Functions from Ordered Pairs

For the relation {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.

• 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}

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)

• {-4, 4, 8, 9}
• {-2, 3, 8, 10}
• {(9, -2) ( 4, 3)}
• {(8, 10) (-4, 8)}

What is the domain of the relation shown in the table?

• {12}

• {6, 18}

• {3, 9, 15, 16}

• {13}

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values
