Find the domain of the relation:

{(–5, –4), (–2, –1), (1, 0), (2, 2), (4, 3)}

a.
{–5, –4, –2, –1, 0, 1, 2, 3, 4}

b.
{–5, –2, 1, 2, 4}

c.
{–4, –1, 0, 2, 3}

d.
{–4, –1, 2, 3}

To work through a problem like this, first find how many ordered pairs you’re given. In this case, it’s 5.

The answer will always match the amount of ordered pairs given, IF no two x-values are the same. For this scenario, each x-value is unique, so you will have an answer with exactly 5 values. This rules out A and D.

From there, just take the x-value of each ordered pair, list ‘em in order, and you get your answer.

B is the correct answer

The person above is right B is the right answer
