Answer 10

the range is the set of y values.

sets do not have duplicates in them.

Answer 11

{-1,1,3}

Answer 12

to do this problem look at your (x,y) pairs. and write down all the y values (2nd number in the pair)
if you get a duplicate number, ignore it (no copies allowed)
whatever is left is the range.
