7.2 Polynomial Functions and Their Graphs Andrew Fisher 8-2
Local 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).
Example Find the Local Minimum and Maximum.
Answers Local Minimum(-3,6) Local Maximum(3,-6)
Increasing and Decreasing Functions F is increasing over an open interval if for every x1
