Notation & Strategy Guide
Domain (\(x\)-values): Left to Right Find leftmost and rightmost \(x\). If an arrow extends infinitely right, use \(x \ge a\). If bounded, use \(a \le x \le b\).
Range (\(y\)-values): Bottom to Top Find lowest and highest \(y\). If opening down from a vertex peak, use \(y \le \text{Max}\). If bounded, use \(\text{Min} \le y \le \text{Max}\).
Notice: All endpoints shown are solid dots •, so always use \(\le\) or \(\ge\).

Self-Check & Reflection
1. Vertex Rule for Quadratics:
When does a quadratic range use \(y \le k\) vs. \(y \ge k\)?
2. Solid Endpoint Strategy:
Why do solid endpoints require \(\le\) and \(\ge\) instead of \(<\) and \(>\)?
