Concept 1: Increasing and Decreasing Function(s)
Concept 1: (extended) – Guidelines for Finding Intervals Let f be continuous on the interval (a, b). To find the open intervals on which f is increasing of decreasing, use the following steps: 1. Locate the critical numbers (by finding the derivative) of f in (a, b) and use these numbers to test intervals 2. Determine the sign of f’(x) at one test value in each interval 3. Based on the sign of f’(x) determine if the function increases or decreases
