Question

Find the domain of the relation:
{(−4, −1), (−2, 1), (0, 1), (2, 3), (4, 0)} (Points : 0.2)
{−1, 0, 1, 3}
{−4, −2, −1, 0, 1, 2, 3, 4}
{−4, −2, 0, 2, 4}
{−4, 0, 2, 4}

Answer 1

Please I need help

Answer 2

In this instance, since you are only looking for domain, you look at the range between all the x-coordinates given.

Answer 3

so for the first one, the domain would be D:{xer| -4 < x < 4}

Answer 4

Does that make sense?

Answer 5

Yes it does thanks @lovethecreation
