To complete the input-output table for the function \( f(x) = - (x + 1)^2 + 4 \), we need to calculate \( f(x) \) for each given value of \( x \).

1. For \( x = -1 \):
\[
f(-1) = -(-1 + 1)^2 + 4 = -0 + 4 = 4
\]

2. For \( x = 0 \):
\[
f(0) = -(0 + 1)^2 + 4 = -1 + 4 = 3
\]

3. For \( x = 1 \):
\[
f(1) = -(1 + 1)^2 + 4 = -2^2 + 4 = -4 + 4 = 0
\]

4. For \( x = 2 \):
\[
f(2) = -(2 + 1)^2 + 4 = -3^2 + 4 = -9 + 4 = -5
\]

Now we can summarize the completed table:

\[
\begin{array}{c|c}
x & f(x) \\
\hline
-1 & 4 \\
0 & 3 \\
1 & 0 \\
2 & -5 \\
\end{array}
\]

**Now to determine which value of \( x \) produces the largest output:**
- \( f(-1) = 4 \)
- \( f(0) = 3 \)
- \( f(1) = 0 \)
- \( f(2) = -5 \)

The largest output is \( 4 \) when \( x = -1 \).

Thus, the answer is:
**x = -1**.
