If this was a -f(x) then it would be odd? I think I understand now..Am I correct?

Algebra
Yes I read them, but misinterpreted them I suppose. So this is an even function because x is being represented rather than y and this would be an even function resulting in a reflection in the y-axis? I will sketch it out.

So I would say that the answer would be that f can be both odd and even then. Am I correct?
