Answer 3

ok so they are paired coordinates where the first value is the x-coordinate and the second value is the y-coordinate
So lets take the first pair in the relation:
(-1,2) so -1 is the x-coordinate and 2 is the y coordinate
Our Domain is our input values also known as our x values or x-coordinate
So in this case it would be all our x-coordinates of our relation

Answer 4

it should be {-1,2,4,6}
