odd function?

@UnkleRhaukus In relation to the graph of f(x), I don't know if that helps

OpenStudy (unklerhaukus):

can i get some background to this question?

OpenStudy (anonymous):

@UnkleRhaukus I am preparing for a test and in my textbook I have the equation x^4-4x^3+3x^2 and they did the sign chart and they made a note to say "note that the sign of f(x) does not change at x=0" So I just wanted to know what happens if it does?
