Identifying Functions from tables, mappings, and ordered pairs

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 paired with it.

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