Question

The range of the following relation: R: {(3, −2), (1, 2), (−1, −4), (−1, 2)} is

{−1, 1, 3}

{−1, −1, 1, 3}

{−4, −2, 2, 2}

{−4, −2, 2}

Answer 1

Range = y-values....*you dont take repeating numbers...so what are all the y-values you have?

Answer 2

Range: {y-values}
Domain: {x-values}

(x, y)

Answer 3

Remember: only count repeating numbers once

Answer 4
