Question
## Problem Statement **Function Analysis:** Let \( f(x) = 8x^3 - 9 \). Determine the open intervals on which \( f \) is increasing or decreasing. Then, identify the \( x \)-coordinates of all relative maxima and minima. **Instructions:** 1. **Increasing Intervals:** Determine where \( f(x) \) is increasing. 2. **Decreasing Intervals:** Determine where \( f(x) \) is decreasing. 3. **Relative Maxima:** Find \( x \)-coordinates for the relative maxima of \( f(x) \). 4. **Relative Minima:** Find \( x \)-coordinates for the relative minima of \( f(x) \). **Input Areas:** - For the increasing intervals, the input field is empty, awaiting user input. - "None" is selected for both the decreasing intervals and relative maxima and minima. **Additional Notes:** - For increasing and decreasing intervals, your response should be a single interval like \( (0,1) \), a list such as \((- \infty, 2), (3,4)\), or "none". - For relative maxima and minima, provide a list of \( x \)-values or indicate "none". **Hint:** Accessible via a clickable link. **Partial Credit:** You can earn partial credit on this problem. **Interactive Elements:** - **Preview My Answers** button - **Submit Answers** button
