Lesson Plan

Description:

This activity is intended to allow students to study the effects of changes to the values of A, B, and C on the graph of the quadratic function when given in standard form, y = ax2 + bx + c 1. As a result of this activity, students will be able to graph a parabola in standard form by determining the vertex and then using the y-intercept and a symmetric point to plot the curve 1. The students will learn how to represent the vertex (h,k) of a quadratic function in terms of a, b, and c when the function is in standard form.

Reviewer Comments:

This exercise uses a graphing calculator to investigate the relation between the vertex form and the standard form for the equation of a parabola. In this context it is an exemplary lesson. Students use the calculator to bypass the intricacies of graphing quadratic functions. This is standard practice now, but what has been lost in the use of calculators is any "number sense" the students might have acquired in doing these tasks manually.
