That's not a polynomial, but an exponential, discretized (x^2 is a polynomial, 2^x an exponential)
In everyday life, I would guess most polynomials you encounter are of order zero or one. Most people would not call those polynomials.
Second order ones you encounter when doing quick math for computing how hard an impact will be, or how far a car accelerating from zero to X in T seconds will go.
