To check the continuity of the function \( f(x) \) at \( x = 2 \), we need to verify the following conditions: 1. The function \( f(2) \) is defined. 2. The left-hand limit (LHL) as \( x \) approaches 2 exists. 3. The right-hand limit (RHL) as \( x \) approaches 2 exists. 4. The left-hand limit and right-hand limit are equal, and both are equal to \( f(2) \). ### Step 1: Find \( f(2) \) ...
