VIDEO: Algebra Nspirations: Quadratic Functions, 1

Topic

Quadratic Functions

Description

The video introduces quadratic functions, explaining their definition, historical origin, and importance in algebra. Key concepts include terms like quadratic term, linear term, and constant term, and the general polynomial form y = ax² + bx + c. It explores how coefficients a, b, and c affect the graph's geometry, including parabolic shapes, symmetry, vertical shifts, and the effects of leading coefficient changes. Practical applications include projectile motion and architectural designs. Visualization with TI-Nspire technology reinforces learning.

This video provides an engaging way to understand the topic of quadratic functions and their real-world applications. The detailed explanations and visual demonstrations help students connect the concepts to problem-solving scenarios.

Teacher’s Script: "Before we begin, let’s think about how quadratic functions appear in everyday life. For instance, they describe the trajectory of a basketball shot or a rocket launch. This video explores these concepts in-depth, offering visual examples and applications. As you watch, note how the graphs change with different coefficients and constants."
