Answer 1

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.
