Question Analysis
This question tests the understanding of evaluating a piecewise function at a specific point, specifically at the boundary where the function changes.

Key Concept Explanation
To evaluate a piecewise function at a specific point, identify which piece of the function applies to that point and then substitute the value into the appropriate expression.

Step-by-step Solution
1. Identify the piece of the function that applies to .
2. Since is in the interval , use the expression .
3. Substitute
