Question 70596
what happens to a second degree when a, b, and c changes?
--------------------
1st: y=ax^2+bx+c yields the graph of a parabola.
a determines how quickly the branches of the parabola spread.
b is a strong determinant of the x-intercepts of the curve.
c is a strong determinant of the vertical level of the lowest or 
   highest point of the parabola.  This point is called the vertex.
