What are the domain and range of the function {(0, 2), (-2, 4), (2, 8), (1, 6), (-5, 0)}?

1. Domain: {2, 4, 8, 1, -5}; Range: {0, -2, 6}

2. Domain: {0, -2, 6}; Range: {2, 4, 8, 1, -5}

3. Domain: {2, 4, 8, 6, 0}; Range: {0, -2, 2, 1, -5}

4. Domain: {0, -2, 2, 1, -5}; Range: {2, 4, 8, 6, 0}

Please help. Is it 4.D? or 1.A? neither?

  1. Hint:
    Domain of a set of ordered pairs is the set of all the "x-values", or the first value of each ordered pair.
    Range is the set of y-values of the ordered pairs.
