Polynomial An expression of finite length Finite= has limit; definite; countable; measurable made up of terms that are only added, subtracted or multiplied comes form poly- (meaning "many") and -nomial (in this case meaning "term") ... so it says "many terms"
Composition of Polynomials Constants Variables Variables with positive exponents can have no variable at all Can have one variable
Whats special about polynomials? If you add polynomials you get a polynomial If you multiply polynomials you get a polynomial
Standard form Those variables with highest exponents go first Descending order of exponents 4 2 x −2x + x
Example Graph of a Polynomial Example: x 4−2x 2+ x
