I have a problem. My teacher gave us the following information: She asked us to graph this, describe the domain and range, and whether it's a function.
I say it's not a function because numbers are repeated in the domain (4). Is that correct? If so I don't think I need to write an equation right?
x y
4 -2
4 -1
4 0
4 1
4 2
4 3
4 4
