The image shows a graph of a piecewise function $f(x)$, with a prompt asking for the value of $f(4)$.

From the graph:

1. Locate $x = 4$ on the x-axis.
2. Find the corresponding point on the graph.
3. The y-coordinate of this point is the value of $f(4)$.

Based on the graph, the point corresponding to $x = 4$ is $(4, -4)$. Therefore, $f(4) = -4$.

Would you like any further details on this, or do you have any other questions?

Here are some related questions for further exploration:

1. What is the value of $f(-2)$ based on the graph?
2. Can you describe the general behavior of the function $f(x)$ as $x$ increases?
3. What is the value of $f(x)$ when $x = 2$?
4. What is the domain and range of the given function?
5. How does the function $f(x)$ behave at the points where it changes direction?

Tip: When reading a graph, always carefully identify the scale of both the x-axis and y-axis to ensure accurate interpretation of points.
