The degree of a polynomial function is the highest exponent to which the dependent variable is raised. For example, f(x) = 4x 5 â x 2 + 5 is a fifth-degree polynomial, because its highest exponent is 5.
A polynomial function has the form , where are real numbers and n is a nonnegative integer. In other words, a polynomial is the sum of one or more monomials with real coefficients and nonnegative integer exponents. The degree of the polynomial function is the highest value for n where an is not equal to 0. Polynomial functions of only one term are called monomials or power functions. A power function has the form . For a polynomial function f, any number r for which is called a zero or root of the function f. When a polynomial function is completely factored, each of the factors helps identify zeros of the function.
