Essential Question Essential Vocabulary What is a polynomial? How do we describe its end behavior? How do we add/subtract polynomials? Essential Vocabulary Polynomial Degree End Behavior Leading Coefficient

Essential Notes Polynomial: One term or the sum/difference of two or more terms. To be a polynomial: Variable Bases Whole number exponents Real number coefficients

The degree of a polynomial is the same as the largest exponent The degree of a polynomial is the same as the largest exponent. We write polynomials in standard form which means write exponents in descending order from left to right. When in standard form, the leading coefficient is the number in the front.

End Behavior Describes the ends of the graph as x approaches ±∞ Even Function: highest exponent is even # LC: + 𝒙→+∞, 𝒚→+∞ 𝒙→−∞, 𝒚→+∞ LC: − 𝒙→+∞, 𝒚→−∞ 𝒙→−∞, 𝒚→−∞

LC: + 𝒙→+∞, 𝒚→+∞ 𝒙→−∞, 𝒚→−∞ LC: − 𝒙→+∞, 𝒚→−∞ 𝒙→−∞, 𝒚→+∞ Odd Function: highest exponent is odd # LC: + 𝒙→+∞, 𝒚→+∞ 𝒙→−∞, 𝒚→−∞ LC: − 𝒙→+∞, 𝒚→−∞ 𝒙→−∞, 𝒚→+∞ x and y same x and y opposite
