Quadratic Explorations

The standard form of a quadratic is y=ax^2+bx+c.  Most students understand the effects of a and c on the graph of the parabola, but what does b do?  I hinted at this problem earlier, but just created and uploaded a GeoGebraTube Web document to model the problem.

In class, that’s about all I give before releasing my students to explore on their own.  As always, my students are required to do two things:  state their conjecture and prove that it works.

Results from my students coming in a future post.
