The domain of the function is roughly -128 ≤ x ≤ 128.

There are three intervals with different behavior:
1. Negative inputs: the output decays towards a limiting value around 8. Domain: -128 ≤ x < 0.
2. Zero input: the output is a very large value. Domain: x = 0.
3. Positive inputs: the output oscillates around 0 with minimal change as x increases. Domain: 0 < x ≤ 128.
