Quadratic Explorations

I first encountered this problem about a decade ago when I attended one of the first USACAS conferences sponsored by MEECAS in the Chicago area.  I’ve gotten lots of mileage from it with my own students and in professional circles.

For a standard form quadratic, y=a*x^2+b*x+c, you probably know how the values of a and c change the graph of the parabola, but what does b do?  Be specific and prove your claim.
