Polynomial Graphs Short Quiz: Tomorrow 1/27/10 (maybe)

Polynomial Functions and Their Graphs There are several different elements to examine on the graphs of polynomial functions: Local minima and maxima:

On the graph above:A local maximum: f(x) = A local minimum: f(x) = Give the Local Maxima and Minima Must use y to describe High and Low

Finding a local max and/or local min is EASY with the calculator! Graph each of the following and find all local maxima or minima: Now describe their end behavior.

Describe the Interval of Increasing and Decreasing Increasing when ___________ Decreasing when _____________ Increasing when ___________ Must use x to describe Left to Right x y (Left to Right) The graph is:

Give the maximums and minimums and describe the intervals of increasing and decreasing, for each of the following:

Give the maximum and minimums and describe the intervals of increasing and decreasing, for each of the following:

Now, let’s do it on our own: For each of the following: sketch the graph find the points at which there is a local max or min describe the intervals in which the function is increasing or decreasing describe the end behavior
