1. **Stating the problem:** We are given a piecewise function $f(x)$ defined by two segments:
- A horizontal line segment from $(-3, -4)$ to $(0, -4)$ with filled endpoints.
- A line segment from an open circle at $(3, -8)$ to a filled circle at $(5, -2)$.
2. **Interpreting the segments:**
- The first segment is constant at $y = -4$ for $x$ between $-3$ and $0$, inclusive.
- The second segment is a line connecting $(3, -8)$ (open circle, so not included) to $(5, -2)$ (filled circle, included).
3. **Writing the piecewise function:**
$$
f(x) = \begin{cases}
-4 & \text{for } -3 \leq x \leq 0 \\
\text{slope} \cdot (x - 3) + (-8) & \text{for } 3 < x \leq 5
\end{cases}
$$
4. **Finding the slope of the second segment:**
$$
\text{slope} = \frac{-2 - (-8)}{5 - 3} = \frac{6}{2} = 3
$$
5. **Equation of the second segment:**
Using point-slope form with point $(3, -8)$:
$$
f(x) = 3(x - 3) - 8 = 3x - 9 - 8 = 3x - 17
$$
6. **Final piecewise function:**
$$
f(x) = \begin{cases}
-4 & -3 \leq x \leq 0 \\
3x - 17 & 3 < x \leq 5
\end{cases}
$$
This matches the graph description with the correct domain intervals and endpoint inclusions.
