Ordinarily, when you find the slope of a line, you need two points.  What about the slope of a parabola?  Well, it doesn't have just one slope; it has infinitely many slopes, one at each point on the graph.  So how are you supposed to calculate a slope that changes at every point.  That's a fine question, and it's one this project seeks to answer.  Realize that upon completing this project, you will have just learned a bit of Calculus.  Now how smart do you feel?

One last reminder:  You may work collaboratively to complete the document above.  Plan a group meeting date, use Skype, Snap Chat, consult the Internet or a teacher (me?), the point is for you to understand the concepts. You'll be applying them on a short quiz in class.  The document above is worth 1/3 of the project grade, and the in-class, independent assessment will be worth 2/3 of the project grade.  (Remember project grades count as major assessments!)
