Quadratic Function Exam Review
This page introduces key concepts for solving quadratic equations and graphing quadratic functions. It covers the fundamental theorem of quadratics, rules for solving equations, and methods for graphing.
Definition: The fundamental theorem of quadratics states that you have as many answers as the greatest roots.
Example: For solving quadratic equations, the page provides examples such as 3k² = 8k - 4, demonstrating the step-by-step process to find solutions.
The page also explains how to graph quadratic equations, including finding the axis of symmetry, vertex, y-intercept, and x-intercepts. It emphasizes the importance of understanding whether the parabola opens upward or downward based on the sign of the leading coefficient.
Highlight: When graphing quadratic equations, pay attention to the sign of the leading coefficient to determine if the parabola opens upward positive or downward negative.
