CCSS.HSF.IF.A.1

The table of values are shown. What is the domain of the relation? From least to greatest.

• (-4,-8,-3)

• (-3,2,6)

• (-8,-4,4)

• (6,2,-3)

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.
