I give out medals!!! The range of the following relation: R: {(3, −2), (1, 2), (−1, −4), (−1, 2)} is... A.) {−1, 1, 3} B.) {−1, −1, 1, 3} C.) {−4, −2, 2, 2} D.) {−4, −2, 2}

OpenStudy (anonymous):

the range is composed of all of your y values in the ordered pair sets.

OpenStudy (anonymous):

so do you know which ones are y?

OpenStudy (anonymous):

... no...im srry, Im a very slow learner and so I take a lot of time to process this

OpenStudy (anonymous):

the ordered pairs represent your x and y coordinates of a point of the graph, they are (x,y) so the first number (x) represents your horizontal location, the second one (y) represents your vertical location, together they are a point's "address".

OpenStudy (anonymous):

ok...

OpenStudy (anonymous):

your domain are all of the x's your range is all of the y's

OpenStudy (anonymous):

so...C?

OpenStudy (anonymous):

your question asks for all of the y's there is no need of including one twice if it shows up more than once

OpenStudy (anonymous):

close

OpenStudy (anonymous):
