CCSS.8.F.A.1

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.

How do you determine if a relation is a function? 

• The vertical line test crosses more than one point on the graph.

• The same y-values are mapped from the same x-values.

• The vertical line test crosses only one point on the graph.

• Each input is related to more than one output.
