## Solving inequalities involving modulus

In this lesson, we’ll look at solving inequalities involving modulus function, and the modulus function is limited to “part” of the expression on either (or both sides ) of the inequality sign.

## Solving inequalities involving modulus sign: |f(x)| > |g(x)| or |f(x)| < |g(x)|

To solve an inequality involving |f(x)| > |g(x)| or |f(x)| < |g(x)| , we can make use of the results: Examples of Solving inequality involving…
