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}

Can anyone help me? Please? :)

Answer 1

Domain is all of the possible x values, right?
You just count all of the different x-coordinates in the list

Answer 2

Oooh okay, thanks :) I wasn't sure what to do.
