Question One: Test Your Understanding of Limits
| x | f(x) |
| 1.9 | 3.9 |
| 1.99 | 3.99 |
| 1.999 | 3.999 |
| 2 | Undefined |
| 2.001 | 0.999 |
| 2.01 | 0.99 |
| 2.1 | 0.9 |

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.
