11. 11 The correct response: 1. 2. A number divided by 6 is equal to that number squared.

12. 12 State the domain and range of the relation {(-4, 3), (-1, -2), (0, -4), (2, 3), (3, -3)}. Is this relation a function?

13. 13 The domain is {-4, -1, 0, 2. 3} The range is (-4, -3, -2, 3} Since each member of the domain is paired with exactly one member of the range, this relation is a function.
