To determine which table indicates that \( y = -f(x) \) represents a reflection over the x-axis, we need to examine how the values of \( f(x) \) and \( -f(x) \) correspond to each other in each table.

1. **Table 1**
- \( f(x) \): \( 2, 0, 3, 1, 6, 2 \)
- \( -f(x) \): \( 0, -1, -2 \)

Here, there are mismatches in the entries.

2. **Table 2**
- \( f(x) \): \( -2, 0, -3, -1, -6, -2 \)
- \( -f(x) \): \( 2, 0, 3, 1, 6, 2 \)

This shows that \( -f(x) \) is the negation of \( f(x) \), which confirms a reflection over the x-axis.

3. **Table 3**
- \( f(x) \): \( -2, 0, -3, 1, -6, 2 \)
- \( -f(x) \): \( 2, 0, 3, -1, 6, -2 \)

Again, this shows matches for some values but does not consistently show that it is a strict negation.

4. **Table 4**
- \( f(x) \): \( 2, 0, 3, -1, 6, -2 \)
- \( -f(x) \): \( 0, -1, -2 \)

Similarly, there are mismatches here.

Upon examination, **Table 2** is the only table where \( -f(x) \) values are exactly the negations of \( f(x) \) values, indicating a consistent reflection over the x-axis.

Thus, **Table 2** corresponds to \( y = -f(x) \).
