The table mode of expressing a function is specifically useful when:
Correct Answer
The domain has a small number of elements and variations are irregular
Explanation
Tables work best when: (a) the domain is small (say 10–20 elements), and (b) no fixed rule exists because of irregular variations — such as empirical scientific data. Tables become impractical for large or infinite domains. They are not needed when a formula is available, and they cannot represent a continuous function on \(\mathbb{R}\).
