Does the following set of ordered pairs represent a function?
 $\left\{\left(1,\ -2\right),\ \left(2,\ 1\right),\ \left(3,\ 6\right),\ \left(4,\ 13\right),\ \left(5,\ 22\right)\right\}$  

• Yes, it represents a function because each input is paired with exactly one output.

• No, it does not represent a function because not every input is paired with exactly one output.

• Yes, because the x-value 1 has two y-values paired with it.

• No, because the x-value 1 has two y-values paired with it.
