Transcript text: Consider the following inequality:
\[
|x|-4<0
\]
Solve the absolute value inequality and express the solution in interval notation.
Solution
Solution Steps
To solve the absolute value inequality \(|x| - 4 < 0\), we need to isolate the absolute value expression and then consider the definition of absolute value. The inequality \(|x| < 4\) means that \(x\) must be within 4 units of 0 on the number line. This translates to the interval \(-4 < x < 4\).
Step 1: Isolate the Absolute Value Expression
Given the inequality:
\[
|x| - 4 < 0
\]
we first isolate the absolute value expression:
\[
|x| < 4
\]
Step 2: Interpret the Absolute Value Inequality
The inequality \(|x| < 4\) means that \(x\) must be within 4 units of 0 on the number line. This translates to:
\[
-4 < x < 4
\]
