Answer 1

To analyze the function \( f(x) = (x + 2)^2 + 1 \) and create a table of values for its reflection over the y-axis (which gives us the values of \( -f(-x) \)), we will first calculate \( f(x) \) for \( x = 0, -1, -2 \), and then find \( -f(-x) \) for those values.

Step 1: Calculate \( f(x) \)

1. For \( x = 0 \): \[ f(0) = (0 + 2)^2 + 1 = 2^2 + 1 = 4 + 1 = 5 \]

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

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

Step 2: Create the table for \( -f(-x) \)

Now, let's compute \( -f(-x) \) for \( x = 0, 1, 2 \):

1. For \( x = 0 \): \[ -f(-0) = -f(0) = -5 \]

2. For \( x = 1 \): \[ -f(-1) = -f(-1) = -2 \]

3. For \( x = 2 \): \[ -f(-2) = -f(-2) = -1 \]

Final Table

Now we can create the final table that summarizes the calculations:

| x | 0 | 1 | 2 | |:---:|:---:|:---:|:---:| | −f(−x) | -5 | -2 | -1 |

This table displays the reflected values for the specified inputs under the transformation \( -f(-x) \).
