Question 2: Write each of the following sets in tabular forms:
\((vi) \; \) \(\{x \mid x\in N\land x+4=0\} \)
Solution:
Solving the equation \(x+4=0\) gives \(x=−4\). Since the set of natural numbers does not include negative numbers, there is no solution. Therefore, the set is empty.
Tabular Form:
\(\{\}\) OR \(\phi\)
