CCSS.HSF.IF.A.1

• Function; it passes the vertical line test.

• Not a Function; it fails the vertical line test.

• Function; it has one x-value paired with 2 y-values.

• Not a Function; it has 2 x-values paired with one y-value.

.

• Function; it has one x-value paired with 2 different y-values.

• Not a Function; it has one x-value paired with 2 different y-values.

• Function; it has 2 different x-values paired with one y-value.

• Not a Function; it has 2 different x-values paired with one y-value.

CCSS.8.F.A.1

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values paired 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.
