Purposeful, Transparent, Contextual, Building Expertise

Purposeful and Transparent Quadratic functions underlie many processes in our everyday lives ranging from physics (trajectory of objects) to business (cost-revenue function). Key to the study of quadratics is optimization – finding a maximum or minimum point. Since students would want to maximize their profit in financial decisions, this lesson focuses on interpreting cost, revenue, and profit functions. Contextual Although this lesson uses a simplified version of the profit modeling conducted by actual businesses, the basic principles are the same. Determining the optimal purchase amounts is one of the key points of success to any business, and can be applied to family business management in areas like grocery shopping or party planning. Building Expertise By using algebra tiles, students extend their knowledge of algebraic representations to geometric representations of quadratic functions. They then apply this understanding to quadratic profit equations, and interpret the key aspects of quadratics in common language.
