Determining Intervals on Which a Function is Increasing or Decreasing

This study guide covers how to determine the intervals where a function is increasing or decreasing using the derivative. It explains that a positive derivative indicates an increasing function, while a negative derivative indicates a decreasing function. The guide emphasizes the importance of critical points (where the derivative is zero or undefined) in identifying these intervals. It provides a walkthrough example, step-by-step instructions, and practice problems to solidify understanding of this concept.
