Solving Quadratic Equations by Graphing

Now that we know how to graph quadratic equations, we began practicing finding the x-intercepts by using an x-y chart to determine critical points of the graph. Be sure to read lesson 9.4 to gain some helpful hints that you might have missed during the class discussion.

Tonight's homework: Lesson 9.4 (21 - 42, First Column Only)--be sure to include graphs in your answers. Also, be ready to present your findings to the class on Wednesday.
