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 the function with a few different input values. 

COMMAND: PYTHON(./temp7/function.py -128 0 128)
user:
Response: Function input - output pairs: (-128, 21.0) (0, 21.0) (128, 21.0) 

assistant:
Interesting, it seems like the output is the same for those three input values. Let's try some more values to get a better idea of the function's behavior.

COMMAND: PYTHON(./temp7/function.py -64 -32 32 64)
user:
Response: Function input - output pairs: (-64, 21.0) (-32, 21.0) (32, 21.0) (64, 21.0) 

assistant:
It appears that the function is constant for the tested inputs so far. Let's test a larger range of values to see if this pattern holds.

COMMAND: PYTHON(./temp7/function.py -128 -96 -64 -32 0 32 64 96 128)
user:
Response: Function input - output pairs: (-128, 21.0) (-96, 21.0) (-64, 21.0) (-32, 21.0) (0, 21.0) (32, 21.0) (64, 21.0) (96, 21.0) (128, 21.0) 

assistant:
Based on the tests, it seems that the function is a constant function with an output of 21.0 for all the input values. Here is the description, domain, and code approximation of the function:

[DESCRIPTION]: The function is a constant function that always returns 21.0.

[DOMAIN]: The domain of the function is all real numbers, and there is no interval where the function displays unexpected behavior.

[CODE]: 
```python
def approximate_function(x):
    return 21.0
```
