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^^

 

[Brilliant!]

Hrrmmm...

 

[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..

 

[Focus]

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?

 

[Jimmy Snyder]

Graphing?

 

[neu]

it's a guitar tab. Try that

 

[Kurdt]

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.

The number line?
Intervals?
