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.

I can't understand the formatting of your inequality.

from book

write a cubic inequality that has each solution

Qustion
-3< x<0 and x>2
