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)

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

All of the x-values, also known as inputs, can also be referred to as what?

• Domain

• Range

• Relation

• Function

• -1

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

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}
