1. **State the problem:** We need to understand and graph the piecewise function:
$$f(x) = \begin{cases} -3x - 12 & \text{for } x \leq -3 \\ 1 & \text{for } x > 5 \end{cases}$$
2. **Explain the function parts:**
- For $x \leq -3$, the function is a linear function $f(x) = -3x - 12$.
- For $x > 5$, the function is a constant function $f(x) = 1$.
3. **Evaluate the linear part at the boundary $x = -3$:**
$$f(-3) = -3(-3) - 12 = 9 - 12 = -3$$
So the line segment ends at the point $(-3, -3)$.
4. **Graph the linear segment:**
- The line $y = -3x - 12$ is valid for all $x \leq -3$.
- For example, at $x = -4$,
$$f(-4) = -3(-4) - 12 = 12 - 12 = 0$$
- So the segment goes from $(-\infty, \infty)$ but restricted to $x \leq -3$, passing through points like $(-4, 0)$ and ending at $(-3, -3)$.
5. **Graph the constant part:**
- For $x > 5$, $f(x) = 1$ is a horizontal line at height 1.
- This segment starts just to the right of $x=5$ (not including $x=5$).
6. **Summary:**
- The graph has two disconnected parts:
- A line segment from $x = -\infty$ up to and including $x = -3$ on the line $y = -3x - 12$.
- A horizontal line segment for $x > 5$ at $y = 1$.
This explains the function and how to graph it.
Final answer: The piecewise function is graphed as described above with the two segments.
