Applications of the Discriminant

Today, we learned that the nature of the simplified discriminant tells you how many, if any, x intercepts the parabola will have. This can be useful when trying to determine where to place the parabola and when trying to find the line of symmetry and vertex of the parabola.

Students had about 34 minutes to work with their partner on the "b" effect on the parabola project. Presentations will include use of the palm with appropriate examples as well as a creative presentation piece. Students will be graded on accuracy of the math presented, speaking skills, and creativity.

Tonight's Homework: Read Lesson 9.6, and then do problems 9 - 20 in this section.
