Solving Absolute Value Inequalities:
- let k represent a positive real number (k > 0)
- To solve |ax + b| > k, solve the following compound inequality:
- ax + b > k or ax + b < -k
- To solve |ax + b| < k, solve the following three-part inequality:
- -k < ax + b < k
- Special Cases of Absolute Value:
- The absolute value of an expression can't be negative
- |a| ≥ 0, for all real numbers a
- The absolute value of an expression can only be 0 if the expression is equal to 0
- |ax + b| = 0, solve the equation ax + b = 0
- The absolute value of an expression can't be negative
