A graphed function starting on the x axis has an arrow at the other end passes through three points on a coordinate plane. The x-axis ranges from negative 9 to 9 in unit increments and the y-axis ranges from negative 11 to 11 in unit increments.

Which table shows that y=−f(x)
results in a reflection over the x-axis?

To determine which table shows that \( y = -f(x) \) results in a reflection over the x-axis, we need to look for a table of values where the \( -f(x) \) values are the negative of the corresponding \( f(x) \) values.

Let's evaluate the provided tables:

1.
```
x -f(x)
-2 0
-3 1
-6 2

x f(x)
-2 0
-3 1
-6 2
```
Here, \( -f(-2) = -0 = 0 \), \( -f(-3) = -1 \), \( -f(-6) = -2 \). This does not reflect the values.

2.
```
x -f(x)
-2 0
-3 -1
-6 -2

x f(x)
-2 0
-3 1
-6 2
```
Here, \( -f(-2) = -0 = 0 \), \( -f(-3) = -1 \), \( -f(-6) = -2 \). This matches the functionality \( -f(x) = -f(x) \) for the corresponding \( f(x) \).

3.
```
x -f(x)
2 0
3 -1
6 -2

x f(x)
2 0
3 -1
6 -2
```
This set gives \( -f(2) = -0 = 0 \), \( -f(3) = 1 \), \( -f(6) = 2 \). This does not reflect properly.

4.
```
x -f(x)
2 0
3 1
6 2

x f(x)
2 0
3 1
6 2
```
Here, \( -f(2) = -0 = 0 \), \( -f(3) = -1 \), \( -f(6) = -2 \). This does not reflect properly.

Based on this evaluation, **the second table** is the only one that correctly shows that \( y = -f(x) \) results in a reflection over the x-axis.

Thus, the answer is the second table:

```
x -f(x)
-2 0
-3 -1
-6 -2

x f(x)
-2 0
-3 1
-6 2
```
