Answer: $2+i5,\ 29$

Step-by-step explanation:

What is the range of the relation?

4vir4ik [10]

Hello!

The range is all of the y-values in a set of points. They are always ordered from least to greatest. It is written as below.

If we look at the y-values on the graph, we get -2,-3,0,and 3. If we order them, we get -3,-2,0, and 3.

This means our answer is B.

I hope this helps!
