3.1 Extrema on an Interval Goal: Determine the behavior of a function f on an interval I.
ABSOLUTE vs RELATIVE (LOCAL) EXTREMA
HOW TO FIND ‘EXTREMA’??? LOOK FOR CRITICAL NUMBERS
Example 1: Find the EXTREMA by finding the critical points:
Example 2: What is happening f(x) = x3 at x = 0? Is it a critical point?
