Classifying Polynomials
Degree of a Polynomial The degree of a polynomial is calculated by finding the largest exponent in the polynomial. In order for a function to be polynomial: -leading coefficient must not be zero -exponents must be whole numbers (no negatives -no variables in the denominator **standard form of a polynomial function has the exponents from greatest to least
