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.

Let's start by running a few experiments on the given function f(x). I will call the function with various input values in the given range.

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, 11.899999999999999) (-64, 11.899999999999999) (0, 11.896800165996478) (64, -6.499999999999999) (128, -6.499999999999999) 

assistant:
Let's test the function on some more input values in between the ones we've already tested to get a better understanding of its behavior.

COMMAND: PYTHON(./temp7/function.py -96 -32 32 96)
user:
Response: Function input - output pairs: (-96, 11.899999999999999) (-32, 11.899999999999999) (32, -6.499999999999999) (96, -6.499999999999999) 

assistant:
Based on the results so far, it seems that there is a different behavior around the x=0. Let's test more input values around this point to narrow down the interval where the behavior changes.

COMMAND: PYTHON(./temp7/function.py -16 -8 -4 -2 -1 1 2 4 8 16)
user:
Response: Function input - output pairs: (-16, 11.899999999999999) (-8, 11.899999999999363) (-4, 11.89999995490929) (-2, 11.899987987186481) (-1, 11.89980392628739) (1, 11.847910432571467) (2, 11.08512932812905) (4, -5.12123578008184) (8, -6.499979000917512) (16, -6.499999999999996) 

assistant:
[DESCRIPTION]: Based on the tested input-output pairs, it seems that the function f(x) behaves as follows:
- For x < 0, the function returns a value very close to 11.9.
- For x > 0, the function returns a value very close to -6.5.
- Around x = 0, the function has a transition between these two values.

[DOMAIN]: The domain of the function is [-128, 128]. There is an interval around x=0 where the function behaves differently. The exact bounds and behavior within this interval are not clear, as the transition happens quickly between -1 and 1.

[CODE]:
```python
def approx_function(x):
    if x < 0:
        return 11.9
    elif x > 0:
        return -6.5
    else:
        return (11.9 + (-6.5)) / 2
```
