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.

Let's start by testing some values to understand the function's behavior.

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, 2150.6493302292124) (-64, 1076.6888876580997) (0, 0.4626649206898268) (64, 1077.3548712001414) (128, 2150.3064216261846) 

assistant:
It seems that the function has some sort of quadratic behavior since the output increases as the input gets farther from zero. Let's test more points and negative positive inputs to find any pattern.

COMMAND: PYTHON(./temp7/function.py -24 -16 -8 8 16 24)
user:
Response: Function input - output pairs: (-24, 403.1301604647969) (-16, 271.4014196694131) (-8, 133.52560204410958) (8, 135.48136065861883) (16, 270.29039032056795) (24, 405.07322448606993) 

assistant:
It appears that the function has symmetric behavior around zero. Let's further investigate the behavior near zero.

COMMAND: PYTHON(./temp7/function.py -4 -2 -1 1 2 4)
user:
Response: Function input - output pairs: (-4, 69.08877796289018) (-2, 32.821844958836124) (-1, 16.5068438404784) (1, 16.135939386066564) (2, 33.023569767156495) (4, 67.58139920068832) 

assistant:
Based on the output, it appears that the function has quadratic behavior and is symmetric around x=0. It seems to have the shape of a parabola.

[DESCRIPTION]: The function is a quadratic function with a parabolic shape, which is symmetric around x=0.

[DOMAIN]: The domain of the function is all real numbers. The function doesn't seem to show any unexpected behavior.

[CODE]: The code to approximate this function would be as follows:

```python
def approx_function(x):
    a = 1
    b = 0
    c = 16
    return a * x**2 + b * x + c
```

To get a better approximation, we can test a few more points to find the coefficients a, b, and c.
