Find the domain and range of the relation {(1, -9), (0, -5), (4, 3), (6, -2)}. Then, determine if the relation is a function.

• Domain: {1, 0, 4, 6}, Range: {-9, -5, 3, -2}, Function: Yes

• Domain: {1, 0, 4, 6}, Range: {-9, -5, 3, -2}, Function: No

• Domain: {1, 0, 4, 6}, Range: {-9, -5, 3, -2}, Function: Not determined

• Domain: {1, 0, 4, 6}, Range: {-9, -5, 3, -2}, Function: Maybe

Find the domain and range of the relation {(5, 2), (-3, 4), (5, -6), (8, 0)}. Then, determine if the relation is a function.
