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 with different values and see the behavior.

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, 25.0) (-64, 25.0) (0, 26.0) (64, 25.0) (128, 25.0) 

assistant:
Let's further investigate the function's behavior by running more values.

COMMAND: PYTHON(./temp7/function.py -100 -50 -25 1 25 50 100)
user:
Response: Function input - output pairs: (-100, 25.0) (-50, 25.0) (-25, 25.0) (1, 26.0) (25, 25.0) (50, 25.0) (100, 25.0) 

assistant:
So far, it seems like the function returns 25.0 for almost all inputs except 0, where it returns 26.0. Let's try some more input values to confirm the behavior, especially around 0.

COMMAND: PYTHON(./temp7/function.py -2 -1 2 3 4 5)
user:
Response: Function input - output pairs: (-2, 26.0) (-1, 26.0) (2, 26.0) (3, 26.0) (4, 25.0) (5, 25.0) 

assistant:
Based on the pairs, I can describe the function:

[DESCRIPTION]: The function returns 25.0 for almost all input values except for inputs in the range of (-2, 2). In that range, the function returns 26.0 for all inputs.

[DOMAIN]: The domain of the function is all real numbers. There's an interval where the function displays unexpected behavior: (-2, 2). In that interval, the function returns 26.0 instead of 25.0.

[CODE]:

```python
def approx_f(x):
    if -2 < x < 2:
        return 26.0
    else:
        return 25.0
```
