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). f(x) is implemented by an MLP.
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 calling the function f(x) on some values to interpret its behavior. 

COMMAND: PYTHON(./temp7/function.py -128 -96 -64 -32 0 32 64 96 128)
user:
Response: Function input - output pairs: (-128, 3311.73193359375) (-96, 2477.4375) (-64, 1643.1431884765625) (-32, 808.84912109375) (0, 106.05274963378906) (32, 3671.74267578125) (64, 7237.4326171875) (96, 10803.1240234375) (128, 14368.8134765625) 

assistant:
It seems that the function has different behaviors in different intervals. Let's further investigate the values between the intervals to get a clearer picture of the function's behavior. 

COMMAND: PYTHON(./temp7/function.py -112 -80 -48 -16 16 48 80 112)
user:
Response: Function input - output pairs: (-112, 2894.58447265625) (-80, 2060.290283203125) (-48, 1225.99609375) (-16, 391.70196533203125) (16, 1888.897705078125) (48, 5454.587890625) (80, 9020.2783203125) (112, 12585.9677734375) 

assistant:
The function seems to have two different behaviors for the intervals of negative and positive input values. For positive x values, the function is increasing and for negative x values, it's decreasing. Let's collect more data points, particularly close to 0, to further understand the function's behavior.

COMMAND: PYTHON(./temp7/function.py -8 -4 -2 -1 1 2 4 8)
user:
Response: Function input - output pairs: (-8, 183.12838745117188) (-4, 78.84161376953125) (-2, 26.69823455810547) (-1, 6.849422454833984) (1, 217.48056030273438) (2, 328.9083557128906) (4, 551.7640380859375) (8, 997.4752807617188) 

assistant:
Based on the additional data, we observe that f(x) has a minimum around x = 0 and increases for both negative and positive x values. Let's describe the function, its domain, and write a Python code to approximate its behavior.

[DESCRIPTION]: The function f(x) has a minimum around x = 0, and it increases for both negative and positive x values. 

[DOMAIN]: The domain of the function is the interval [-128, 128]. There is no unexpected behavior or numeric bounds necessary.

[CODE]:
```python
def approx_f(x):
    if x < 0:
        return 106.05274963378906 - 25 * abs(x)
    else:
        return 106.05274963378906 + 25 * abs(x)
```
