we have
\(n < -2\) -------> inequality A
The solution of the inequality A is the interval------> (-∞,-2)
All real numbers less than \(-2\)
\(n\geq 4\) -------> inequality B
The solution of the inequality B is the interval------> [4,∞)
All real numbers greater than or equal to \(4\)
The solution of the compound inequality A or B is equal to
Solution A+Solution B
(-∞,-2) U [4,∞)
therefore
the answer in the attached figure
