Case 1: Graphing
5 graphs at once.
Let's look at the graphs for the following parabola
for different values of a, b, and c.
5 different values of a when b=1 and c=0
5 different values of b when a=1 and c=0
5 different values of c when a=1 and b=1
It is obvious to see that from these
graphs a, b, and c all change the graphs drastically. It appears that a
affects the width of the parabola, b affects the location of the vertex
both horizontally and vertically, and c affects the vertex vertically.
