Algebra Quiz 3.1: Relations & Functions

Which relation does the mapping show?

• {(0, 1), (1, 2),(3, 4)}

• {(1, 0), (2, 1), (2, 2), (4, 3)}

• {(0, 1), (1, 2), (2, 2), (3, 4)}

• {(1, 0), (2, 1), (4, 3)}

CCSS.8.F.A.1

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.
