5th Order Polynomials

summary: 

A fifth order polynomial can change its directions as this one does three times.

description: 

The input is in yellow and goes through the origin. The polynomial in red has real coefficients. Perhaps a different polynomial could switch directions 5 times, although I have yet to construct one.
