we have
[tex]n < -2[/tex] -------> inequality A
The solution of the inequality A is the interval------> (-∞,-2)
All real numbers less than [tex]-2[/tex]
[tex]n\geq 4[/tex] -------> inequality B
The solution of the inequality B is the interval------> [4,∞)
All real numbers greater than or equal to [tex]4[/tex]
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
