If |x| > a:
Then x a
Step-by-Step Breakdown of the Formula
Understanding the variables in the formula helps clarify the solution process:
- |x|: This represents the absolute value of the variable x. The absolute value indicates the distance of x from 0 on a number line, regardless of direction.
- a: This is a positive constant. It determines the range and constraints applied to x in the inequality.
Calculation Process for |x| < a
- Identify the absolute value inequality. For example, consider |x| < 5.
- Recognize the constraints from the inequality: -5 < x < 5.
- Write the solution in interval notation: (-5, 5).
Calculation Process for |x| > a
- Identify the absolute value inequality. For example, |x| > 3.
- Translate the inequality into separate parts: x 3.
- Express the solution in interval notation: (-∞, -3) ∪ (3, ∞).
Example Calculation
Let’s consider an example using the absolute value inequality |x| < 4.
