Here is the graph of the piecewise function $f(x)$:

• For $x < 0$, $f(x) = -1$ is a constant value.
• For $0 \leq x \leq 4$, $f(x) = 2x - 8$ is a linear function.
• For $x > 4$, $f(x) = \sqrt{x - 4}$ is a square root function.

Notice the discontinuities and the different slopes as the function transitions between different segments.

Additional Questions

1. Is $f(x)$ continuous at $x = 0$ and $x = 4$?
2. Can we calculate the left-hand and right-hand limits at $x = 0$ and $x = 4$?
3. How does $f(x)$ behave as $x \to \infty$?
4. What is the derivative of each piece of the function in its respective domain?
5. Can you determine if the function is increasing or decreasing in each region?

Tip

For piecewise functions, always check the limits and continuity at transition points, as these often reveal key properties of the function.
