You know, we make these sorts of schemes:

_________________-1__________4__________->x

x+1- - - - - - - - - - 0------------------------

x-4- - - - - - - - - - - - - - - - - -0------------

(x+1)(x-4)-----------0- - - - - - -0------------

What do you call this?

The reason why I want to know, is to find out how to make this in MathType^^

yes, but what do I call that way to decide when f(x)<0?

The numbers are random, for the purpose for my question..

going to calculus (and assuming that's something to do with polynomials) few other terms are

What do you call it in your first language?
 
Graphing?

I don't know mathtype but if you want to produce something similarly formatted to what you have its most likely going to be some sort of array.

It took me a while to realize that this is what he means. I would definitely call this graphing.
