From the given outputs, the function appears to yield large, negative values for both negative and positive inputs. The value is less negative around 0. The function also seems to have some sort of symmetry.

[DESCRIPTION]: The function f(x) produces primarily negative outputs for both negative and positive inputs, with the least negative values occurring near 0. The function exhibits symmetric properties in its behavior.

Now, I will write Python code that approximates the behavior of the function.
