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 some initial values. 

COMMAND: PYTHON(./temp7/function.py -128 0 1 64 128)
user:
Response: Function input - output pairs: (-128, -723.0808969866144) (0, 60.23907666566077) (1, 68.5507641703422) (64, 495.37687442731544) (128, 930.4652999176237) 

assistant:
We have some initial data points for the function, let's test more values to understand the function behavior.

COMMAND: PYTHON(./temp7/function.py -64 -32 -16 -8 0 16 32 64 128)
user:
Response: Function input - output pairs: (-64, -330.08491247212595) (-32, -134.97767345587184) (-16, -36.62817096500959) (-8, 12.08201737672709) (0, 60.07534013692943) (16, 170.57612867921185) (32, 279.329786154197) (64, 496.7849568440145) (128, 931.4924435187288) 

assistant:
Let's further analyze the function behavior between [-32, 32].

COMMAND: PYTHON(./temp7/function.py -32 -24 -16 -8 0 8 16 24 32)
user:
Response: Function input - output pairs: (-32, -135.18384286810263) (-24, -86.48853217524794) (-16, -36.61561183946829) (-8, 11.870940748632433) (0, 60.95929460297937) (8, 115.08342894359868) (16, 170.58408463076051) (24, 223.27034575052951) (32, 278.4970876427131) 

assistant:
Based on these results, let's provide a description of the function:

[DESCRIPTION]: The function seems to be a piece-wise linear or quadratic function. When x is negative, the output increases as x increases. When x is positive, the output seems to increase at a different rate. The output increases as the input value x increases, but the increase appears to be more significant for positive input values. 

[DOMAIN]: The function's domain covers the interval [-128, 128]. No unexpected behavior or specific interval has been identified where the function may behave differently.

Now, let's approximate this behavior with code:

[CODE]:
```
def approx_function(x):
    if x < 0:
        return x * 2 + 60
    else:
        return x * 3 + 60
```
Please note that the approximated function might not be an exact replica of the original, but it should provide a reasonable approximation.
