Question

The domain of the following relation: R: {(6, −2), (1, 2), (−3, −4), (−3, 2)} is

{−3, −3, 1, 6}

{−4, −2, 2, 2}

{−4, −2, 2}

{−3, 1, 6}

Answer 1

The domain is the set of all the x-values, or 1st coordinates, of the ordered pairs. So look at your list of ordered pairs, and pluck out each 1st coordinate. There is no need to list a repeated element twice in the domain.

Answer 2

lol ok so D?

Answer 3

yes
