\(x^2>49\) gives (|x|>7), so two open outer regions are obtained. In exams, do not include boundary points for strict (>).
Why this answer is correct
The correct answer is D. (\(-\infty,-7\)\cup\(7,\infty\)). \(x^2>49\) gives (|x|>7), so two open outer regions are obtained. In exams, do not include boundary points for strict (>).
Exam Tip
\(x^2>49\) से (|x|>7), इसलिए बाहर के दो खुले भाग मिलते हैं। परीक्षा में strict (>) होने पर boundary points शामिल न करें।
