Hi, your job is to interpret a function f(x) that is implemented in the ./temp2/function.py script. f(x) takes numerical inputs.
All you can do is call f(x) on a value of x by running PYTHON(./temp2/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(./temp2/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.

[DESCRIPTION]: The function f(x) appears to be a quadratic function with a decreasing quadratic term. It has a large positive value for negative inputs and a large negative value for positive inputs. The function seems to have a concave-down shape.

[DOMAIN]: The function is defined for all real numbers. There does not seem to be any unexpected behavior in the domain.

[CODE]: 

```python
def f(x):
    return x ** 2 - 100000000 * x
```

This code defines a quadratic function with a decreasing quadratic term and a large negative coefficient on the linear term.
