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.

CCSS.8.F.A.1

Does the graph represent a function? Does it pass the vertical line test?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values
• No, because there are not enough dots to tell
• Yes because the dots are all  red
