Based on the results, we can observe that the function seems to behave differently for positive and negative values. Let's describe the behavior of the function.

[DESCRIPTION]:
The function f(x) appears to be a piecewise function. It seems to perform a different operation for negative inputs as opposed to positive inputs. For negative values, f(x) decreases in magnitude as x increases, while for positive values, f(x) increases in magnitude as x increases.
