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 running the function on some values to understand its behavior.

COMMAND: PYTHON(./temp7/function.py 0 1 2 3 4 5 6 7 8 9 10)
user:
Response: Function input - output pairs: (0, 7.9) (1, 35.6) (2, 63.3) (3, 93.0) (4, 123.7) (5, 153.4) (6, 183.1) (7, 211.8) (8, 241.5) (9, 272.2) (10, 302.9) 

assistant:
Let's try running the function on negative values as well.

COMMAND: PYTHON(./temp7/function.py -1 -2 -3 -4 -5 -6 -7 -8 -9 -10)
user:
Response: Function input - output pairs: (-1, -18.860000000000003) (-2, -42.620000000000005) (-3, -64.38000000000001) (-4, -90.14) (-5, -114.89999999999999) (-6, -136.66000000000003) (-7, -162.42000000000002) (-8, -186.18) (-9, -208.94) (-10, -231.7) 

assistant:
Let's try running the function on some values with larger magnitudes to gather more information about its behavior.

COMMAND: PYTHON(./temp7/function.py 20 30 40 -20 -30 -40)
user:
Response: Function input - output pairs: (20, 599.9) (30, 894.9) (40, 1191.9) (-20, -467.3) (-30, -707.9) (-40, -943.5) 

assistant:
Based on the input-output pairs, the function seems to behave like a linear function. Let's try to approximate the behavior with a linear function y = mx + b, where m is the slope and b is the intercept.

[DESCRIPTION]: The function f(x) is a linear function that increases with a positive slope.

[DOMAIN]: The domain of the function is all real numbers. There doesn't seem to be an interval with unexpected behavior based on the input-output pairs we have tested.

To find the approximate slope and intercept, let's use two points from the function's output (0, 7.9) and (1, 35.6).

m = (35.6 - 7.9) / (1 - 0) = 27.7

b = 7.9 (the intercept)

[CODE]:
```python
def approx_f(x):
    m = 27.7
    b = 7.9
    return m * x + b
```

Let's run the approximation on some input values to confirm the behavior.

COMMAND: PYTHON(./temp7/function.py -50 -25 25 50)
