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.

Alright, let's start by running the function with some different inputs to start understanding its behavior.

COMMAND: PYTHON(./temp7/function.py -128 0 128)
user:
Response: Function input - output pairs: (-128, 3545.6) (0, 0.0) (128, 3545.6) 

assistant:
Interesting. Let's try some more inputs, including negative and positive odd and even numbers, to understand if there's any pattern.

COMMAND: PYTHON(./temp7/function.py -127 -64 64 127)
user:
Response: Function input - output pairs: (-127, 3517.9) (-64, 1772.8) (64, 1772.8) (127, 3517.9) 

assistant:
It looks like the function is symmetrical for positive and negative inputs, and values are increasing as we move away from 0. To further investigate, let's try some fractional inputs.

COMMAND: PYTHON(./temp7/function.py -0.5 0.5 1.5 4.5)
user:
Response: Function input - output pairs: (-0.5, 13.85) (0.5, 13.85) (1.5, 41.55) (4.5, 124.64999999999999) 

assistant:
The symmetry is consistent for fractional inputs as well. The function value increases with the absolute value of the input. Let's investigate further by trying some more fractional inputs.

COMMAND: PYTHON(./temp7/function.py -2.5 -1.5 2.5 3.5)
user:
Response: Function input - output pairs: (-2.5, 69.25) (-1.5, 41.55) (2.5, 69.25) (3.5, 96.95) 

assistant:
Based on the observed input-output pairs, f(x) appears to be a symmetrical function with respect to the y-axis, as reflected in the symmetry observed for both positive and negative inputs. The function value appears to increase as we move further away from 0.

Below is a description of the observed function:

[DESCRIPTION]: f(x) is a symmetrical function with respect to the y-axis. The output increases with the absolute value of the input.

[DOMAIN]: The domain of f(x) is the real numbers between [-128, 128]. There is no unexpected interval behavior within this domain.

[CODE]:
```python
def approx_f(x):
    return abs(x) * 27.7
```

The constant 27.7 was approximated from the first input-output pair: (1.5, 41.55) [41.55/1.5 ≈ 27.7]
