When there is a common first difference (constant pattern in outputs), the function is ...

• Linear

• Quadratic

• Neither

• Not a function

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values paired 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.
