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 get an initial understanding of the function's behavior.

COMMAND: PYTHON(./temp7/function.py -10 0 10)
user:
Response: Function input - output pairs: (-10, 4.5) (0, 1271.82) (10, 22.4) 

user:
Response: Function input - output pairs: (-10, 4.5) (0, 1271.82) (10, 22.4) 

assistant:
Let's test some more values to better understand the function's behavior.

COMMAND: PYTHON(./temp7/function.py -100 50 25 -25 -50 100)
user:
Response: Function input - output pairs: (-100, 4.5) (50, 22.4) (25, 22.4) (-25, 4.5) (-50, 4.5) (100, 22.4) 

assistant:
We should further investigate the interval between [-25, 25]. Let's test some additional input values in this range.

COMMAND: PYTHON(./temp7/function.py -25 -20 -15 -10 -5 0 5 10 15 20 25)
user:
Response: Function input - output pairs: (-25, 4.5) (-20, 4.5) (-15, 4.5) (-10, 4.5) (-5, 4.5) (0, 1271.82) (5, 22.4) (10, 22.4) (15, 22.4) (20, 22.4) (25, 22.4) 

assistant:
Based on the inputs and their corresponding outputs, the function seems to have different behavior around the x = 0 value. Let's test a few more points between -1 and 1.

COMMAND: PYTHON(./temp7/function.py -1 -0.5 0 0.5 1)
user:
Response: Function input - output pairs: (-1, 4.5) (-0.5, 4.5) (0, 1271.82) (0.5, 22.4) (1, 22.4) 

assistant:
Based on the experiments, we can describe the function as follows:

[DESCRIPTION]: The function f(x) has a piecewise behavior. At x = 0, the function has an unexpectedly high output. For x < 0, the output is constant at 4.5. For x > 0, the output is constant at 22.4.

[DOMAIN]: The domain of the function is [-128, 128]. The interval with unexpected behavior is at x = 0, where the output is much higher than the behavior observed in other parts of the domain.

[CODE]:
```python
def approx_func(x):
    if x < 0:
        return 4.5
    elif x == 0:
        return 1271.82
    else:
        return 22.4
```
This code approximates the observed behavior of the function.
