About the Unit and the Lesson This lesson aims to give students an understanding of how the roots of a function on a graph can be used to formulate that function. It is hoped that students will be able to find ways of completing this.

Created by GradeAmathhelp.com, all rights reserved. Determine if the following are functionsвЂ¦ Write вЂњfunctionвЂќ or вЂњnot functionвЂќ on the line I have students complete the 3 examples for the Quadratic Functions given in Vertex Form, Standard Form, and Intercept form. I also have students write down the notes with each one. I do not explain the different forms at this time. I want students to complete the foldable to refer back to in the next activity, and to use later in this unit.

I. Quadratic Functions A. The basics The graph of a quadratic function is a parabola. A parabola for a quadratic function can open up or down, but not left or right. The vertex is either the highest or lowest point on the graph depending on whether it opens up or down. If the parabola opens down, the vertex is the highest point. y x Vertex/Minimum Vertex/ Maximum Axis of Symmetry Parabolas 2.1 Transformations of Quadratic Functions For use with Exploration 2.1 Name _____ Date _____ Essential Question How do the constants a, h, and k affect the graph of the quadratic function gx ax h k() ( )=в€’+2?

In particular, they identify the real solutions of a quadratic equation as the zeros of a related quadratic function. Students learn that when quadratic equations do not have real solutions the number system must be extended so that a solution exists, analogous to the
