Determine Function Maps

Determine whether the set of ordered pairs represents y as a function of x. Explain your reasoning. {(–3, –27), (–2, –18), (–1, –9), (0, 0), (1, 9), (2, 18), (3, 27)} The set does/does not represent a function because...

Determine if the graph represents y as a function of x. Explain your reasoning.

The graph does/does not represent a function because ...

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.
