What is the domain of the following relation?? {(-1,2),(2,5),(4,9),(6,11)} I need to know how to do this for my proficiency.
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
it should be {-1,2,4,6}
