**Category:** Calculus  
**Subtype:** Function Analysis  
**Problem Description:** Determine the intervals where the function \(f(x)\) is increasing based on its derivative \(y'\).  

**Summary:** The problem provides a table showing the behavior of the derivative \(y'\) of the function \(f(x)\) across different intervals. You need to identify the interval(s) where the function is increasing (where \(y' > 0\)). The options given are specific intervals on the real number line.
