2. Polynomials f(x) = anxn + an-1xn-1 + … + a1x + a0 n is the Degree
Definition: A polynomial is a function of the form
f(x) = anxn + an-1xn-1 + … + a1x + a0
an ≠ 0, All exponents are whole numbers, and All coefficients are real numbers
an is the Leading Coefficient
n is the Degree
a0 is the constant term

3. Polynomials
A polynomial is written in standard form when the terms are written in descending order of exponents from left to right
