2. 3.1 Extrema on an Interval
Goal: Determine the behavior of a function f on an interval I.

3. ABSOLUTE vs RELATIVE (LOCAL) EXTREMA

5. HOW TO FIND ‘EXTREMA’???
LOOK FOR CRITICAL NUMBERS

7. Example 1: Find the EXTREMA by finding the critical points:

9. Example 2: What is happening f(x) = x3 at x = 0?
Is it a critical point?
