From these experiments, we can see that the function appears to be a square wave with a range of [-128, 128]. The function takes a numerical input, x, and returns a value that is either negative, positive, or zero, depending on the interval in which x falls.

The domain of the function is -128 to 128, with an interval where the function displays unexpected behavior between -4 and 4. Within this interval, the function appears to be a square wave that oscillates between positive and negative values.

Here is a Python code that approximates the behavior of the function:
```
def f(x):
    if x < -4:
        return -x**2
    elif x >= -4 and x <= 4:
        return x**2 - 16
    else:
        return x**2
```
This code defines a function f(x) that takes a numerical input x and returns a value based on the interval in which x falls. For x < -4, the function returns -x**2. For -4 <= x <= 4, the function returns x**2 - 16. For x > 4, the function returns x**2.

The function f(x) can be described as follows:
