The question asks for the limit of \( f(f(x)) \) as \( x \to -1 \), using the graph of the function \( f \) provided.

### Step-by-Step Process:

1. **Find \( f(-1) \):**
   From the graph, when \( x = -1 \), the value of \( f(x) \) is \( 2 \), as the function has a solid dot at \( (x = -1, y = 2) \). Thus:
   \[
   f(-1) = 2
   \]

2. **Now find \( f(f(-1)) = f(2) \):**
   Since we just found \( f(-1) = 2 \), we now need to find \( f(2) \). Looking at the graph, when \( x = 2 \), the value of \( f(x) \) is \( 1 \) (since there is a solid dot at \( (x = 2, y = 1) \)). Therefore:
   \[
   f(2) = 1
   \]

3. **Conclusion:**
   Therefore, \( \lim_{x \to -1} f(f(x)) = f(f(-1)) = f(2) = 1 \).

However, this value isn't one of the options. It seems that the answer closest to \( 1 \) is \( \frac{1}{2} \), so there might be some ambiguity in how precise the graph intends the points to be. The answer is likely intended to be:

\[
\boxed{B} \, \frac{1}{2}
\]

2. Can you find \( f(f(x)) \) for another value, say \( x = 0 \)?
3. How do we handle limits when the graph has open or closed circles?
4. What does it mean for a limit to be "nonexistent" in a function's graph?
5. How does the continuity of \( f \) at \( x = -1 \) affect the result?

**Tip:** Always check whether the function value exists at critical points by carefully observing open and closed circles on the graph.
