FORMS OF LINEAR INEQUALITIES

There are 3 forms of linear inequalities :

1. Set notation form


2. Interval notation form


3. Number line form

SET NOTATION FORM

Formal way of expressing the solution

Example : solution for x > 2 is { x : x > 2 }

This reads as “the set of all x such that x is

greater than 2"

INTERVAL NOTATION FORM

is the symbol represents “element of”

Form of inequalities :

1.Set notation form Parantheses : exluded ()

2. Interval notation form Brackets : included []


3. Number line form
