Question Analysis
This question tests the understanding of ensuring continuity at a boundary point for a piecewise function, which involves equating the left-hand limit and the right-hand limit at the boundary.

Key Concept Explanation
For a piecewise function to be continuous at a boundary point, the value of the function from both sides of the boundary must be the same.

Step-by-step Solution
1. Identify the piece of the function that applies to :
Since and , use the first piece
