Finding equation from inequality

My teacher taught us question where you try to find the equation from an inequlity like

-3__<__x__<__0 **And** x__>__2

=

x^3+x^2-6x __>__0

But what if the question is **Or**

Does it change the outcome in these style of questions?

The book with all my homework uses __And__ does that effect the outcome of these types of questions?

If so how...I understand the difference between and/or but how does it effect the answer? I tried a question as if it was an "or" question and it worked but I would like input thanks so much.
