- Demonstrate an understanding of linear and quadratic inequalities
- single variable (e.g., 3x – 7 ≤ -4, x2 – 5x + 6 > 0)
- domain and range restrictions from problems in situational contexts
- sign analysis: identifying intervals where a function is positive, negative, or zero
- symbolic notation for inequality statements, including interval notation
