what is the answer? @owlet

owlet · Answer

only thing you have to do is look at the given points and give the y-coordinates. Don't you wanna learn how to do it?

anonymous · Answer

yes but I'm very confused. can you teach me but also give me the answer??

x corrdinates are also called the domain
and y-coordinates are called the range.

For example you are given a point (2, 5 ) , the range is 5

Now with your question, let's look at your first point: (3, -5)
which one is your y-coordinate?
