Introduction
Algebra II is a college-prep math course designed for students that successfully completed Geometry.  The students study higher level concepts of Algebra and Trigonometry.  The successful completion of this course will meet the pre-requisite for Pre-Calculus.
Subject :  Algebra II
Topic:      Quadratic Graphs,Their Equations, and Coefficients
Grade Level:  9-12(All students who meet the pre-requites)
Student Lesson name and URL: ctap295.ctaponline.org/~llopez/student/
Standards Addressed

Algebra II: Standard 9.0

Students demonstrate and explain the effect that changing a coefficient has on the graph of quadratic functions; that is, students can determine how the graph of a parabola changes as a, b, and c vary in the equation  y = a(x - b)^2 + c

Instructional Objectives
 After completing this lesson the students will be able to 

(a)  write the equation of the quadratic function by studying the graph and

(b)  be able to graph different quadratic functions where the coefficients a,b,and c vary in the equation  y = a(x - b)^2 + c

(c) be able to explain the effect that changing a coefficient has on the graph of quadratic functions

Student Activities
Insert brief summaries of your introductory, enabling, and culminating activities. Insert links to online resources in your text and insert links to activities on your student lesson web site.
Introductory Activity
The students will review graphing quadratic equations using graph paper and pencil.  The students will graph quadratic equations of the form 

y = a( x - b )^2+c.  (A link to the student introductory activity)
