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 evaluating the function at some values to get a general idea of its behavior. 

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, 3.5) (-64, 3.5) (0, -451.55) (64, -6.0) (128, -6.0) 

assistant:
Interesting, let's test some more values to get a better understanding of the function.

COMMAND: PYTHON(./temp7/function.py -126 -62 2 66 130)
user:
Response: Function input - output pairs: (-126, 3.5) (-62, 3.5) (2, -6.0) (66, -6.0) (130, -6.0) 

assistant:
Let's try a few more values to narrow down the interval where the function's output seems to change.

COMMAND: PYTHON(./temp7/function.py -60 -40 -20 -10 -5 10 20 40 60)
user:
Response: Function input - output pairs: (-60, 3.5) (-40, 3.5) (-20, 3.5) (-10, 3.5) (-5, 3.5) (10, -6.0) (20, -6.0) (40, -6.0) (60, -6.0) 

assistant:
It looks like we have found some interval of interest. Let's narrow it down a bit more.

COMMAND: PYTHON(./temp7/function.py -6 -4 -2 0 2 4 6)
user:
Response: Function input - output pairs: (-6, 3.5) (-4, 3.5) (-2, 3.5) (0, -451.55) (2, -6.0) (4, -6.0) (6, -6.0) 

assistant:
Based on the function input-output pairs, we can now describe the function f(x):

[DESCRIPTION]: The function f(x) appears to output 3.5 for most negative values, -6.0 for most positive values, and an unexpected -451.55 at 0. 

[DOMAIN]: The domain of the function is all real numbers. There is a specific interval around 0 where the function behaves differently: from -1 to 1 (both excluded). In this interval, the function outputs an anomalous value of -451.55 at x=0.

[CODE]: Here's a Python code that approximates the behavior of the function:

```python
def approx_f(x):
    if x <= -1:
        return 3.5
    elif x >= 1:
        return -6.0
    else: # -1 < x < 1
        return -451.55
```
