### Graphing Piecewise Functions

In this exercise, you are asked to graph the piecewise function \( f(x) \) defined as follows:

\[ f(x) = \begin{cases} 
3x - 2 & \text{if } x < 2 \\ 
(x - 2)^2 + 4 & \text{if } 2 \leq x < 3 \\ 
5 & \text{if } x \geq 3 
\end{cases} \]

### Instructions:
1. **Plot the function** for each segment on the coordinate plane.
2. **Identify and label all intercepts** (x-intercepts and y-intercepts).

### Graph Segments Explanation:

- **Segment 1: \( y = 3x - 2 \)**  
  - This linear function is defined for \( x < 2 \). 
  - Find the intercepts:
    - **Y-intercept** is where \( x = 0 \): \( y = 3(0) - 2 = -2 \).
    - **X-intercept** is where \( y = 0 \): \( 0 = 3x - 2 \implies x = \frac{2}{3} \).

- **Segment 2: \( y = (x - 2)^2 + 4 \)**  
  - This quadratic function is defined for \( 2 \leq x < 3 \). 
  - Since the domain starts at \( x = 2 \), you need to check the continuity:
    - Evaluate at \( x = 2 \): \( y = (2 - 2)^2 + 4 = 4 \).
    - Evaluate at \( x = 3 \): \( y = (3 - 2)^2 + 4 = 5 \).

- **Segment 3: \( y = 5 \)**  
  - This constant function is defined for \( x \geq 3 \). 
  - It remains constant at \( y = 5 \).

### Instructions for Graphing:
- Use a different color or style of line (solid, dashed) for each segment to clearly differentiate between the piecewise functions.
- Ensure that you include open or closed circles to mark the endpoints of each segment accurately.
- Label the intercepts and any points of interest, especially transitions between the different function definitions.
