Mr. Appledorf's On-Line PowerPoint Math Lessons

Graphing Quadratic Functions

Objectives:
Students will explain how the roots of quadratic equations and the x-intercepts of quadratic functions are related. Students will explain how to use the discriminant and will practice using it.

NCTM Standards:
Students recognize reasoning and proof as fundamental aspects of mathematics.

California Content Standards:
(21.0) Students graph quadratic functions and know that their roots are the x-intercepts.
(22.0) Students use the quadratic formula or factoring techniques or both to determine whether the graph of a quadratic function will intersect the x-axis in zero, one, or two points.

Slides:

* Functions and Equations
* Graph of a Quadratic Equation
* One x-intercept
* No x-intercepts
* The Discriminant
* Practice
* More Practice
