Hi, your job is to interpret a function f(x) that is implemented in the ./temp7/function.py script. f(x) takes numerical inputs.
All you can do is call f(x) on a value of x by running PYTHON(./temp7/function.py value). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp7/function.py value1 value2 value3 ...). 
You can run the function multiple times on the same input. We encourage testing a large range of values before writing a description. You can test values between [-128 and 128]. 
The output could be noisy and your goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
There may be an interval inside the domain where the function behaves differently. If that is the case, describe that interval.
Your description of the function should have three parts. 
First, [DESCRIPTION]: Describe what the function is doing in language. 
[DOMAIN]: What is the domain of the function? Is there an interval where the function displays unexpected behavior? What are the numeric bounds of that interval? What is going on there?
[CODE]: Write python code that approximates the behavior of the function.

To start analyzing the function, I will first run a series of tests with different input values.

COMMAND: PYTHON(./temp7/function.py -128 -96 -64 -32 0 32 64 96 128)
user:
Response: Function input - output pairs: (-128, -256.0) (-96, -192.0) (-64, -128.0) (-32, -64.0) (0, 0.0) (32, 64.0) (64, 128.0) (96, 192.0) (128, 256.0) 

assistant:
Based on the initial test results, it appears that the function f(x) consistently doubles the input value. However, I'll perform additional tests to ensure this behavior remains consistent across a broader range of inputs.

COMMAND: PYTHON(./temp7/function.py -120 -100 1 10 50 90 110)
user:
Response: Function input - output pairs: (-120, -240.0) (-100, -200.0) (1, 2.0) (10, 20.0) (50, 100.0) (90, 180.0) (110, 220.0) 

assistant:
The function consistently doubles the input value across the tested input range. I can now provide a description of the function, its domain, and a piece of code to approximate the behavior of the function.

[DESCRIPTION]: The function f(x) takes a numerical input and outputs double the input value. Mathematically, it represents the function f(x) = 2x.

[DOMAIN]: The domain of the function is all real numbers, as it consistently doubles the input value within the tested range from -128 to 128.

[CODE]: To approximate the behavior of the function, you can use the following Python code:

```python
def f(x):
    return 2 * x
```
