A polynomial function is any function in the form of:

It is defined as a monomial or a sum of monomials

Things to know

• The degree of a polynomial is the largest exponent

• Standard form of a polynomial is written from highest exponent to lowest

• The leading coefficient is the coefficient on the term with the highest degree
