Answer 1

To find the table that represents \( y = f(-x) \), we need to reflect the original function \( y = f(x) \) across the y-axis. This means that for every positive x-value in the original function, we will find the corresponding value at the negative of that x-value in the new function.

Let's assume the original function \( f(x) \) has the following points based on the descriptions:

1. \( f(1) = 2 \)
2. \( f(2) = 0 \)
3. \( f(3) = 2 \)

For \( f(-x) \), we look for:

- \( f(-1) = f(1) = 2 \)
- \( f(-2) = f(2) = 0 \)
- \( f(-3) = f(3) = 2 \)

Based on this logic, the corresponding values for \( y = f(-x) \) would be:

- When \( x = -1 \), \( f(-(-1)) = f(1) = 2 \)
- When \( x = -2 \), \( f(-(-2)) = f(2) = 0 \)
- When \( x = -3 \), \( f(-(-3)) = f(3) = 2 \)

Now, let's evaluate the provided options:

- The correct table for \( y = f(-x) \) should show:
- \( x = -1 \), \( f(-x) = 2 \)
- \( x = -2 \), \( f(-x) = 0 \)
- \( x = -3 \), \( f(-x) = 2 \)

Based on this evaluation, the correct response is:

**x f(−x)**
-1 2
-2 0
-3 2

So, the correct answer is:
- \( x f(−x) \)
- -1 2
- -2 0
- -3 2
