The domain of the function is the set of numerical inputs for which the function is defined. In this case, the domain appears to be the range of values between -128 and 128. Within this range, there might be an interval where the function displays unexpected behavior or exhibits a different pattern. To identify this interval, we can explore the behavior of the function across different values.

To analyze the output and identify any unexpected behavior, we can call the function on various inputs within the domain using the PYTHON command. Let's start by testing some values.
