Generally, polynomials are functions of

f(x) = anxn + an-1xn-1 + ... + a1x + a0,


n is the degree of the polynomials and it must be positive integer,
an is the leading coefficient of the polynomials and
ai are coefficients.

Table below shows some examples of polynomials:

FunctionDegreeLeading CoefficientType of Polynomial
5x + 115Linear
25 - x22-1Quadratic

The domain for polynomial is always (-∞,∞); while the range is also (-∞,∞) for odd degree but for even degree we have to find it according to the function given.
