Question

The domain 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

same thing as last time but with x values instead of y

Answer 2

thank you sir!

Answer 3

so option one @zzr0ck3r

Answer 4

correct

Answer 5

now go back to that last question and notice that it is impossible to draw a vertical line that goes through the graph more than once, thus it IS a function. If you could hit the graph more than once with a vertical line then it is NOT a graph.
