The domain of the function is the set of all real numbers. From the experiments, we can observe that the function behaves as expected for most values of x. However, there seems to be an interval where the function displays unexpected behavior. There is a jump in the output values when x changes from -128 to -122 and from 122 to 128. It appears that the function has different behavior in the interval [-128, -122] and [122, 128].
