Pre-AP Calc 10/19/09

Class summary and notes!

The first 2o (it was ACTUALLY 25) minutes of class we spent taking the Suppercorrection quiz. Then we worked in our books on page 134, going over a matching-function-to-equation exercise. We saw the definition of polynomial function, which we won't need to learn, phew (it's REALLY complicated-looking). Then we went on to learning about polynomial functions. WolframAlpha!

•Linear functions are a special type of polynomial functions

•Every polynomial function has the property that they always are ARN

•As x approaches infinity, the function itself also approaches infinity

•As x approaches -infinity, the function also approaches -infinity.

•An odd degree means that the end lines go in opposite directions.

•An even amount of turning points means the end lines go in opposite directions.

•The amount of turning points is AT MOST one less than the exponent.

•Double roots (or roots with multiplicity).

•Even routes make a smooch.
