A polynomial is a mathematical expression involving a sum of nonnegative integer powers in one or more
variables multiplied by coefficients. A polynomial in one variable with constant coefficients can be written
in a n x n  a n 1 x n 1  ...a 2 x 2  a1 x  a 0 form where an  0 , the exponents are all whole numbers, and the
coefficients are all real numbers.
1. What are whole numbers?
2. What are real numbers?
3. Decide whether each function below is a polynomial. If it is, write the function in standard form. If it is
not, explain why.
a. f ( x)  2 x 3  5x 2  4 x  8
b. f ( x)  2 x 2  x 1
c. f ( x)  5  x  7 x 3  x 2
d. f ( x) 

* A polynomial function in standard form is written in descending order of exponents from left to right.
* The degree is the highest exponent and will help us classify the polynomial.
* Coefficients are all real numbers. A leading coefficient is the number in front of the leading term when
in standard form.
* A constant term is a number without a variable.
Ex. f(x) = 2 + 3x
Ex. f(x) = 3x + x2 – 4 – 3x3
