The domain of the function below is 
{ (18, 5) (6, 9) (-14, 1)}

• {1, 5, 9}
• {-14, 6, 18}
• {-14, 1, 5, 6, 9, 18}
• {-14, 6, 8}

What is the range of the relation?

• {1, 4}

• {-5, -4}

• {-5, -4, 1, 4}

• {-5, 1, 4}

a set of ordered pairs

• relation

• mapping

• function

• function notation

The set of all first coordinates (or x-values) of a relation or function

• ordered pair

• domain

• range

• zeros

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.

Which set of values is a function?
