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:
Let's start by running the function on a few different inputs. I will test -128, -64, 0, 64, and 128.

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, -13251.7) (-64, -3350.9) (0, -3.7) (64, -3210.1) (128, -12970.100000000002) 

assistant:
It seems that the output values are quite large and negative. I will test a few more points to get a better understanding of the function.

COMMAND: PYTHON(./temp7/function.py -96 -48 -24 24 48 96)
user:
Response: Function input - output pairs: (-96, -7482.1) (-48, -1899.7) (-24, -490.9) (24, -438.1) (48, -1794.1000000000001) (96, -7270.9) 

assistant:
The outputs are still mostly negative, and it appears that there might be some symmetry in the function. I will test a few smaller values now.

COMMAND: PYTHON(./temp7/function.py -10 -5 5 10)
user:
Response: Function input - output pairs: (-10, -94.7) (-5, -29.2) (5, -18.2) (10, -72.7) 

assistant:
From the given outputs, the function appears to yield large, negative values for both negative and positive inputs. The value is less negative around 0. The function also seems to have some sort of symmetry.

[DESCRIPTION]: The function f(x) produces primarily negative outputs for both negative and positive inputs, with the least negative values occurring near 0. The function exhibits symmetric properties in its behavior.

Now, I will write Python code that approximates the behavior of the function.

[CODE]:
```python
def approx_function(x):
    return -(x ** 2 + x * 3 + 2)
```
