The domain of the function is the set of all numerical values. However, there seems to be a specific interval where the function displays unexpected behavior. In this interval, the function output goes from a very small value to a significantly larger value before returning to a small value. This suggests that there may be a point of inflection or a significant change in behavior within this interval.

[Numeric Bounds of Unexpected Behavior]: Based on the experiments, the interval where the function displays unexpected behavior seems to be between -100 and 100.
