3 9

Answer 1

please help

Answer 2

range is also y-values..

Answer 3

heh... that's kind of weird wording, as "numbers" don't have ranges, but relations do, and relations are collection of pairs (x,y). So I'm assuming that these values for x and y are a relation.

Then the range just means the set of all the SECOND coordinates, e.g., the y values.
