Tell whether the following is a function. If not explain why. {(-3, 5), (0, 7), (0, 6), (4, 1)}. It's not a function, right? I don't see any possible pattern.

    it's not a function because we have 0 twice in the domain.

    To be a function each x value must have a unique y value, so it isnt a function because x=0 has 2 y-values

    Alright thank you! I didn't think that it was, and I forgot the rule about x values not being repeated. And it's getting late and I've been doing math all day, excuses excuses... Thank you @UsukiDoll for putting it into terms that will work in the assignment also. Just curious I want to make sure, it doesn't matter if y values repeat, right?

    the x values matter more if we're given a problem like this.
