Determining the Equation of a Quadratic Function
“`html📘 Math Lesson: Determining the Equation of a Quadratic Function
Use zeros, vertices, points, tables, and projectile models to build quadratic equations. Read carefully, solve calmly, and enjoy the challenge! 🌟
Forms: y = ax² + bx + c | y = a(x – h)² + k | y = a(x – r₁)(x – r₂)
Lesson Focus ✨
✅ Given zeros: use y = a(x – r₁)(x – r₂).
✅ Given vertex and point: use y = a(x – h)² + k and solve for a.
✅ Given three points: substitute each point into y = ax² + bx + c.
✅ Projectile problems: the highest point is the vertex.
