Question

How do you express intervals as inequalities such as (-4,-2)?

Answer 1

Answer:

x+4=0

x+2=0

Hope dis helps u..

Answer 2

Let's assume we are dealing with the interval between

−4

and

−2

on the real line, exclusive of the upper and lower end points.

This means we are considering all points

x

on the real line between -4 and -2 exclusive. That is all points

x∈R

where

−4<x<−2

NB: If we were considering the interval including the upper and lower end points, this could be written:

−4≤x≤−2. :x∈R
