our teacher's making us do it for hwk.

eg, for a quadratci you could say it was a parabola/U shaped...

thnx

I have a few points to give for the best answer

-------
I give up on trying to use knowledgeable quotes as
signatures, they always turn out tacky...

I don't know, I would say it's like a parabola with the second quadrant reflected about the x-axis...

But I mean, that's just a basic cubic... A cubic for something like y = x(x-1)(x+1) would look different... more wavy...
