Why this answer is correct
The correct answer is C. (\(-\infty,-4]\cup[4,\infty\)). \(x^2\ge 16\) means \(|x|\ge 4\), giving two closed outer regions. In exams, include (-4) and (4) for \(\ge\).
Exam Tip
\(x^2\ge 16\) में \(|x|\ge 4\), इसलिए बाहर के दो closed भाग मिलते हैं। परीक्षा में \(\ge\) होने पर (-4) और (4) शामिल करें।
