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.
