Investigating Quadratics, Part Two

Because I have been asked to attend a district meeting on Thursday, the final part of the tests covering concepts 11 and 12 will be delayed until Thursday (thus making the plans for the guest teacher much simpler for this large class). Students worked on the second and third parts of the quadratic investigation today. Here's a recap of the assignment:

Part 1: y = ax^2
Part 2: y = x^2 + c
Part 3: y = x^2 + bx

For each part, make a table of data (5 points minimum) for 6 examples of the basic equation, graph the six functions on one large graph, and write an analysis describing how the variable (a, b, or c) changes the graph.

Tonight's Homework: Continue working on the quadratic equation investigation. Plan ahead, especially if you will be at the track meet on Thursday. The last part of concept test 11 will be given in class tomorrow. See unit 11 in the home book if you want to review.
