Consider the piecewise function f(x) defined above, whose behavior near x=2 is represented in the table and graph. 

Part A: Write the limit notation for the value that f(x) approaches as x approaches 2 from the left, and state its value based on the table and graph. 

Part B: Write the limit notation for the value that f(x) approaches as x approaches 2 from the right, and state its value based on the table and graph. 

Part C: Does the limit of f(x) as x approaches 2 exist? Express your conclusion using proper limit notation and explain why or why not.
