Which set of values is a function? (9,5) (10,5) (9,-5) (10,-5), (3,4) (4,-3) (7,4) (3, 8), (6,-5) (7, -3) (8, -1) (9, 1), (2, -2) (5, 9) (5, -7) (1, 4)

Back

(6,-5) (7, -3) (8, -1) (9, 1)

Front

Is the relation a function? Why?

Back

No, because the x-value 11 has two y-values pair with it.

Front

Front

What does it mean for a function to be one-to-one?

Back
