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.

Alright, let's start by testing some inputs for the f(x) implemented in the ./temp7/function.py script.

COMMAND: PYTHON(./temp7/function.py -128 -64 -32 -16 -8 -4 -2 -1 0 1 2 4 8 16 32 64 128)
user:
Response: Function input - output pairs: (-128, -696.64) (-64, -352.32) (-32, -180.16) (-16, -94.08) (-8, -51.04) (-4, -29.52) (-2, -18.759999999999998) (-1, -13.379999999999999) (0, -8.0) (1, 7.6) (2, 23.2) (4, 54.4) (8, 116.8) (16, 241.6) (32, 491.2) (64, 990.4) (128, 1988.8) 

assistant:
Let's test some more values to make sure we have a more comprehensive understanding of the function.

COMMAND: PYTHON(./temp7/function.py -127 -96 -80 -40 -20 -10 -5 3 5 10 20 40 80 96 127)
user:
Response: Function input - output pairs: (-127, -691.26) (-96, -524.48) (-80, -438.4) (-40, -223.2) (-20, -115.6) (-10, -61.8) (-5, -34.9) (3, 38.8) (5, 70.0) (10, 148.0) (20, 304.0) (40, 616.0) (80, 1240.0) (96, 1489.6) (127, 1973.2) 

assistant:
Based on the output data we have so far, it seems that the function has different behavior for positive and negative input values. Let's examine the input-ouput pairs more closely.

For negative inputs, the output appears to closely follow this equation: f(x) = x * (x + 8)

For positive inputs, the output appears to closely follow this equation: f(x) = x * 14.8

Now I will provide the function description, domain details, and the approximated Python code.

[DESCRIPTION]: The function appears to behave differently for positive and negative input values. For negative values, it seems to behave like a quadratic function with the equation f(x) = x * (x + 8). For positive values, it behaves like a linear function with the equation f(x) = x * 14.8.

[DOMAIN]: The domain of the function is all real numbers. There is no interval with unexpected behavior, but there are separate behaviors for positive and negative inputs. For negative inputs, the interval is x < 0, and for positive inputs, the interval is x > 0.

[CODE]:

```python
def approximated_function(x):
    if x < 0:
        return x * (x + 8)
    else:
        return x * 14.8
 ```
