Determine the domain/range and if the relation is a function. Table: x: 5, 1, 3, 7, 3; y: 5, -2, -1, 3, 3

• Domain: {1, 3, 5, 7}, Range: {-2, -1, 3, 5}, Not a function

• Domain: {1, 3, 5, 7}, Range: {-2, -1, 3, 5}, Is a function

• Domain: {1, 3, 5, 7, 3}, Range: {-2, -1, 3, 5}, Not a function

• Domain: {1, 3, 5, 7}, Range: {-2, -1, 3, 5}, Is a function

Determine the domain/range and if the relation is a function. Table: x: -6, -3, 0, 3, 6; y: 2, 0, 1, 5, -4

• Domain: {-6, -3, 0, 3, 6}; Range: {2, 0, 1, 5, -4}; It is a function.

• Domain: {-6, -3, 0, 3, 6}; Range: {2, 0, 1, 5, -4}; It is not a function.

• Domain: {2, 0, 1, 5, -4}; Range: {-6, -3, 0, 3, 6}; It is a function.

• Domain: {-6, -3, 0, 3, 6}; Range: {2, 0, 1, 5, -4}; It is not possible to determine.
