What is the domain of the table?

• {-2, 0, 2, 3}

• {-4, 0, 1, 3}

• {-4, -2, 0, 1, 2, 3}

• { (0, 0), (2, -4), (3, 3), (-2, 1) }

What is the range of the table?

• {-2, -1, 0, 1, 8}

• {3, 5, 7 , 9, 0}

• {-2, -1, 0, 1, 3, 5, 7, 8, 9}

• {(-2, 3), (-1, 5), (0, 7), (1, 9), (8, 0)}

For the function {(5,4), (8,-2), (0,-4), (-2,4)}, write the domain and range.

• D: {0, -2, 5}

  R: {-4, -2, 4}

• D:{-2, 0, 5, 8}

  R:{-4, -2, 4}

• D:{-4, -2, 4}

  R:{0, -2, 5, 8}

• D:{-2, 0, 4}

  R:{-4, 5, 8}

Is the relation a function? Why?

• Yes, because the y-value 4 has two x-values paired with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the y-value 4 has two x-values paired with it.

• No, because each x-value has only one y-value paired with it.

Which graph does NOT represent a function?

• F

• J

• H

• G

Is this a function or not?
