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:
I will start by running the function on some inputs to understand its behavior. 

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, -1945.6) (-64, -972.8) (0, -0.0) (64, -972.8) (128, -1945.6) 

assistant:
It seems that the function is linear and decreasing with a negative output for all the tested values. I will test more values across the inputs range.

COMMAND: PYTHON(./temp7/function.py -100 -50 -25 25 50 100)
user:
Response: Function input - output pairs: (-100, -1520.0) (-50, -760.0) (-25, -380.0) (25, -380.0) (50, -760.0) (100, -1520.0) 

assistant:
Based on the input-output pairs, the function appears to have an absolute linear behavior with a slope of 15.2 and does not pass through the origin. I will now provide the description, domain, and code for the given function.

[DESCRIPTION]: The function is an absolute linear function with a slope of 15.2, not passing through the origin.

[DOMAIN]: The domain of the function is all real numbers, as it accepts inputs from -128 to 128. There are no intervals of unexpected behavior within this domain.

[CODE]:
```python
def approx_function(x):
    return -15.2 * abs(x)
```
