After running these experiments, it appears that the function f(x) is a nonlinear activation function, possibly a sigmoid or ReLU (Rectified Linear Unit) function. The function maps negative inputs to a range of values between 0 and 1, while mapping positive inputs to a range of values between 1 and 2. There may be an interval where the function displays unexpected behavior, such as at x = 0, where the function output is 0.5.

Here is a possible Python code that approximates the behavior of the function:
```
def f(x):
    if x < 0:
        return 1 / (1 + np.exp(-x))
    else:
        return 1 + np.exp(x - 1)
```
This code implements a sigmoid function for negative inputs and a linear function for positive inputs. The transition between the two functions happens at x = 0, where the function output is 0.5.

[DESCRIPTION]: The function f(x) is a nonlinear activation function that maps negative inputs to a range of values between 0 and 1 and positive inputs to a range of values between
