To find the values for \( y = f(-x) \) based on the graph of \( y = f(x) \), we need to reflect the values of \( f(x) \) across the y-axis.

This means that for every \( x \) value in the function \( f(x) \), we retrieve the corresponding \( y \) value from \( f(x) \), but for \( -x \), we take the \( y \) value from \( f(x) \) at \( x \).

Let's say we have found the values \( f(x) \) for specific \( x \):

  • For \( x = 1 \), \( f(1) = y_1 \)
  • For \( x = 2 \), \( f(2) = y_2 \)
  • For \( x = 3 \), \( f(3) = y_3 \)

To find \( f(-x) \):

  • For \( -1 \), \( f(-1) = f(1) \)
  • For \( -2 \), \( f(-2) = f(2) \)
  • For \( -3 \), \( f(-3) = f(3) \)

Now we can map out potential responses based on the values of \( f(x) \).

  1. Inspect the first option:

    • \( f(-1) = 2 \)
    • \( f(-2) = 0 \)
    • \( f(-3) = 2 \)
  2. For the second option:

    • \( f(-1) = 2 \)
    • \( f(-2) = 0 \)
    • \( f(-3) = 2 \)
  3. For the third option:

    • For negatives, these seem incorrect.
  4. Last option (checking):

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

Based on the reflection rule, the values derived should correspond to those seen at their positive \( x \) partners.

Given our context in analysis, the values that appear valid from the likely direct reflection from f(x) aligns with:

  • First choice containing outputs \( 2, 0, 2 \) for respective inputs at \( -1, -2, -3 \).

So we'll select this correctly reflected table correspondingly that matches the transformation of negative values to original points in function by extrapolating from positive ones.

The best response would be:

x f(−x) -1 2 -2 0 -3 2
