17.2 Polynomial Functions and Their Graphs Andrew Fisher 8-2
2Local Minimum and Maximum Local minimum and maximum are the highest and lowest points in their “neighborhood” on the graph.2 points on either side of the minimum or maximum f(x1) and f(x2) are less than or greater than f(a).
5Increasing and Decreasing Functions F is increasing over an open interval if for every x1<x2 in the interval, f(x1)<f(x2) F is decreasing over an open interval if for every x1<x2 in the interval, f(x1)>f(x2)
