Which of the following sets represents the range of the function shown? {(–3, 4), (5, 11), (9, –1), (10, 13)} {–3, 5, 9, 10} {–1, 4, 11, 13} {(4, –3), (11, 5), (–1, 9), (13, 10)} {–3, –1, 4, 5, 9, 10, 11, 13}

2! Is it 2?? :O

zepdrix (zepdrix):

Oh :p

OpenStudy (anonymous):

omg that seems reasonable :D

zepdrix (zepdrix):

The range is the set of outputs, or y values. Recall that y is the second coordinate in the pair. \(\Large\rm (x,\color{red}{y})\) So we're looking for the set that contains all of these red values.

OpenStudy (anonymous):

ok

zepdrix (zepdrix):

It's going to be a list of single elements, so we can immediately cross off option 3, those are still ordered pairs for some reason. We only want the y's.

OpenStudy (anonymous):

ok

zepdrix (zepdrix):

So which one? What do you think? :d I'm not gonna answer it for you XDDD

OpenStudy (anonymous):

B

OpenStudy (anonymous):

no,no,no

OpenStudy (anonymous):

D

zepdrix (zepdrix):

D has listed 8 elements. So that must be the set of all the x's and all the y's. That's no bueno. We want only the y's. Since we have 4 sets of order pairs, we should have a set of 4 elements in our answer.
