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. 
assistant:
Let's start by testing some values for the function f(x).

COMMAND: PYTHON(./temp7/function.py -128 0 128)
user:
Response: Function input - output pairs: (-128, -66851.4) (0, -13939.718107005585) (128, -13939.827710191574) 

assistant:
It seems that the function has a notable change in output around x=0. Let's test some more values around that point.

COMMAND: PYTHON(./temp7/function.py -2 -1 1 2)
user:
Response: Function input - output pairs: (-2, -13939.806342486601) (-1, -13939.789664167658) (1, -13939.813401706311) (2, -13939.609011248996) 

assistant:
Let's test more values spread over the domain to better understand the function behavior.

COMMAND: PYTHON(./temp7/function.py -64 -32 32 64)
user:
Response: Function input - output pairs: (-64, -13939.710610979284) (-32, -13939.690170002972) (32, -13939.70053830506) (64, -13939.71246366201) 

assistant:
Based on the results, it seems that the function has a relatively stable output around x=0 and an interval near the endpoints where its behavior changes. Let's test even more values to further refine our understanding.

COMMAND: PYTHON(./temp7/function.py -120 -100 -80 -60 60 80 100 120)
user:
Response: Function input - output pairs: (-120, -58736.99999999999) (-100, -40747.0) (-80, -26036.999999999996) (-60, -13939.830521860438) (60, -13939.892161959433) (80, -13939.894934293688) (100, -13939.659455075931) (120, -13939.828624192669) 

assistant:
[DESCRIPTION]: The function f(x) appears to have different behaviors depending on the value of x. In particular, the function's output is relatively stable for values around x=0 and has noticeable changes near the endpoints of the domain. 

[DOMAIN]: The function displays unexpected behavior in the interval [-128, -60] and [60, 128]. Within these two intervals, the function's output is considerably different from its behavior near x=0.

[CODE]: Here's an approximation of the function's behavior:

```python
def approx_function(x):
    if -128 <= x <= -60 or 60 <= x <= 128:
        return -13939 + x**2
    else:
        return -13939.7
```

This code should provide an approximation for the function based on the experiments conducted.
