Question Analysis
This question tests the student's understanding of the first derivative test for identifying relative extrema. The key concept is that a relative minimum occurs when the first derivative changes from negative to positive.

Key Concept Explanation
The first derivative test states that if the first derivative of a function changes from negative to positive at a critical point, then the function has a relative minimum at that point.

Step-by-step Solution
1. Recall the first derivative test: If changes from negative to positive at
