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.

To get started, I will first run the function with various input values. I will start by running the command with input values 0, 1, -1, 2, -2, 10, -10, 100, and -100.

COMMAND: PYTHON(./temp7/function.py 0 1 -1 2 -2 10 -10 100 -100)
user:
Response: Function input - output pairs: (0, 0.0) (1, 79.0) (-1, -79.0) (2, 158.0) (-2, -158.0) (10, 790.0) (-10, -790.0) (100, 7900.0) (-100, -7900.0) 

assistant:
The initial tests indicate that the function might be a linear function with a slope that could be 79. I will run more tests with various input values to confirm this hypothesis.

COMMAND: PYTHON(./temp7/function.py 3 -3 5 -5 20 -20 50 -50 128 -128)
user:
Response: Function input - output pairs: (3, 237.0) (-3, -237.0) (5, 395.0) (-5, -395.0) (20, 1580.0) (-20, -1580.0) (50, 3950.0) (-50, -3950.0) (128, 10112.0) (-128, -10112.0) 

assistant:
Based on the additional input-output pairs, it seems that my hypothesis is correct. The function appears to be a linear function with a slope of 79.

[DESCRIPTION]: The function is a linear function that multiplies the input value by 79.

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

[CODE]:
```python
def approx_function(x):
    return 79 * x
```
