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:
To begin the experiments, I will call the function on multiple input values. 

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, nan) (-64, nan) (0, -inf) (64, 847.6237604505753) (128, 988.7110538590046) 
Error occurred, please try again (some of the input values might be undefined)
assistant:
It seems like the function has issues with inputs of -128 and -64. I will try testing a few more input values, avoiding -128 and -64.

COMMAND: PYTHON(./temp7/function.py -63 -32 0 32 63)
user:
Response: Function input - output pairs: (-63, nan) (-32, nan) (0, -inf) (32, 706.5364670421461) (63, 844.4182463511462) 
Error occurred, please try again (some of the input values might be undefined)
assistant:
It appears that the function also has problems with -63 and -32 as input values. Let's try a few positive input values to further explore the function's behavior.

COMMAND: PYTHON(./temp7/function.py 1 2 4 8 16)
user:
Response: Function input - output pairs: (1, 1.1) (2, 142.1872934084292) (4, 283.27458681685846) (8, 424.3618802252877) (16, 565.4491736337169) 

assistant:
Now we can observe the function's behavior for positive input values. Let's test some negative input values excluding -128, -64, -63, and -32.

COMMAND: PYTHON(./temp7/function.py -127 -60 -30 -15 -5)
user:
Response: Function input - output pairs: (-127, nan) (-60, nan) (-30, nan) (-15, nan) (-5, nan) 
Error occurred, please try again (some of the input values might be undefined)
assistant:
As we can see, the function doesn't seem to work with negative input values either. I will try testing the function on some specific input values to narrow down the problematic inputs.

COMMAND: PYTHON(./temp7/function.py -1 0 1)
user:
Response: Function input - output pairs: (-1, nan) (0, -inf) (1, 1.1) 
Error occurred, please try again (some of the input values might be undefined)
assistant:
Based on our experiments, the function does not work with negative input values and takes on an undefined output (nan). For the input value 0, the output is negative infinity (-inf). For positive input values, the function seems to produce finite output values.

Now I will provide the description, domain, and approximate code for the function based on our findings.

[DESCRIPTION]: The function seems to not work for negative input values, resulting in undefined output values (nan). At the input value of 0, the output is negative infinity (-inf). For positive input values, the function outputs finite values.

[DOMAIN]: The domain of the function is restricted to positive input values only since negative input values produce undefined outputs (nan) and 0 results in negative infinity (-inf).

[CODE]:
def approx_function(x):
    if x <= 0:
        return float('nan')
    else:
        return 1.1 + (x - 1) * 141.0872934084292
