Why it matters

• Understand how parabolas model motion, profit, area, and design.
• Switch between standard, vertex, and factored forms to reveal meaning quickly.
• Use axis of symmetry and vertex to interpret graphs and optimize outcomes.
• Solve quadratics by factoring, completing the square, and the quadratic formula.
• Connect solutions to x-intercepts, turning points, and real-world constraints.
• Build confidence for Algebra 2, SAT/ACT, and physics-style problems.
