# I need to know what something's called in English

#### Compaq

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^^

#### rootX

I see that you have roots
and then you make quadratic equation that has same roots

#### Compaq

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

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

Turning point?

#### rootX

going to calculus (and assuming that's something to do with polynomials) few other terms are
point of inflection, maxima, minimum points

#### Compaq

Yes, thanks, but what do you call the entire form?

#### Brilliant!

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.
