### Exploring Piecewise Functions and Limits

In this module, we will analyze the behavior of a piecewise function and determine its limits at specific points. The function is defined as follows:

\[ 
f(x) = 
\begin{cases} 
5 - x, & x < 3 \\
3, & x = 3 \\
2x - 3, & x > 3 
\end{cases}
\]

### Graphical Representation of \(f(x)\)

The graph provided alongside the function definition depicts the piecewise nature of \(f(x)\). Key components of the graph include:

- A linear segment represented by \(5 - x\) for \(x < 3\).
- A point at \(x = 3\) where \(f(x) = 3\).
- Another linear segment denoted by \(2x - 3\) for \(x > 3\).

The graph transitions through these different parts at \(x = 3\), reflecting the defined conditions.

### Limit Analysis

#### Part (a): Determine \(\lim_{x \to 3^-} f(x)\)

Here, we focus on the limit of \(f(x)\) as \(x\) approaches 3 from the left-hand side (denoted as \(3^-\)). Select the correct answer:

- **Option A**: \(\lim_{x \to 3^-} f(x) = \)

(Simplify your answer, considering the expression \(5 - x\) as \(x\) approaches 3 from the left.)

- **Option B**: The limit does not exist.

#### Part (b): Determine \(\lim_{x \to 3^+} f(x)\)

Next, consider the limit of \(f(x)\) as \(x\) approaches 3 from the right-hand side (denoted as \(3^+\)). Select the correct answer:

- **Option A**: \(\lim_{x \to 3^+} f(x) = \)

(Simplify your answer based on the expression \(2x - 3\) as \(x\) approaches 3 from the right.)

- **Option B**: The limit does not exist.

### Analysis Conclusion

To finalize the examination, compare the left-hand limit and the right-hand limit at \(x = 3\):

- If both limits exist and are equal, we conclude that the
