Quadratic Function Example

Quadratic Function Example

Author: Aaron Nunley

The student will graph a quadratic function, identify the line of symmetry, the vertex, and the domain and range of the function.

This video demonstrates how students in Algebra I can graph a quadratic function using a t-chart and an understanding of the line of symmetry and vertex.  Students are then presented with how to find the domain and range of the function and how to write them using function notation.  The ability to factor is not required for using this method.

Graphing Quadratic Functions

This video describes how to graph a Quadratic function using the line of symmetry and the vertex formula. Students are taught how to use the reflection to cut the amount of work in half and are then shown how to determine the domain and range of the function and write them in function notation. No factoring is utilized.
