Click on the applet to begin.
Slide the values of the three zeros 'a','b' and 'c' to see how they change the graph.
What happens when you make a "double root"?
A triple root?

Graph of Third Degree Polynomial

y=(x-a)(x-b)(x-c)

a = 5 (slider from -5 to 5, step 0.1)
b = 2 (slider from -5 to 5, step 0.1)
c = -1.5999999999999996 (slider from -5 to 5, step 0.1)
f(x) = (x - a) (x - b) (x - c)
A: (a, 0)
B: (b, 0)
C: (c, 0)
