Quadratics

Introduction to Quadratics (00:00 - 01:15)

  • Discussion on the transition from linear equations to quadratic equations.

  • Identification of the x-squared term as the defining characteristic of a quadratic.

The Anatomy of a Parabola (01:15 - 02:45)

  • Exploration of the 'a' value and how it determines if the graph opens upward (positive) or downward (negative).

  • Explanation of how the magnitude of the coefficient affects the width and stretch of the curve.

  • Definition of the vertex as the central turning point of the graph.

Intercepts and the Quadratic Formula (02:45 - 04:00)

  • Analyzing x-intercepts (roots/zeros) and the different ways a parabola can interact with the x-axis.

  • A brief overview of the Quadratic Formula as a tool for solving equations that cannot be factored easily.
