Covered across all four courses, quadratic functions are studied through multiple representations — standard, factored and vertex form. Students solve quadratic equations using factoring, completing the square and the quadratic formula, and use the discriminant to determine the nature of roots. In AA the algebraic treatment is more rigorous; in AI the emphasis is on using quadratics as models for real-life situations such as projectile motion and cost functions, with technology used to find roots and key features.
