3rd Order Polynomials

summary: 

A third order polynomial can have three events appearing in an animation at once (this is not required, but represents a maximum).

description: 

The input which travels through the origin is shown in yellow. A cubic polynomial is in red. The polynomial continues its march down and to the left after a brief moment of indecision. The coefficients are all real, so the red and yellow are all in the same line.
