**Definition:** A polynomial function is a function with many terms. A polynomial can be classified by the number of terms it has (binomial, trinomial, etc.) or by its degree (linear, quadratic, cubic, quartic, etc.).

A polynomial has the form, where *n* is the degree of the polynomial.

Mr. Lee's Example Photo:

Description: So, it turns out that Mr. Lee's cat Loki has whiskers that are mostly described by cubic functions. Loki must be a very mathematically advanced cat. I couldn't get Geometer's Sketchpad to draw the function in factored form so I ended up entering some points in my tricked out TI-84SE and then did cubic regression to find the equation of his whisker.
