Determine If Relation Is A Function

Determine if the relation is a function. Explain.

• Yes. Each domain element is paired with exactly one range element.

• No. Each domain element is paired with exactly one range element.

• Yes. 6 is paired with both 9 and 10.

• No. 6 is paired with both 9 and 10.

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.

Does this mapping diagram represent a function?

• No, because an input value goes to multiple output values

• Yes, because each input goes to one and only one output
