SUMMARY
The domain of an antiderivative is not always equal to the domain of the original function but is always a subset. In the discussion, it is established that if a function \( g \) has a derivative \( h \), then \( \text{dom}(h) \subseteq \text{dom}(g) \). For example, the function \( f(x) = |x| \) has a domain of all real numbers, while its derivative \( f'(x) \) has a domain of all real numbers except 0. This illustrates that while the domain of the derivative is a subset, it does not imply equality.
