यदि (x) वास्तविक संख्या है और \(x\notin[2,5]\), तो संख्या रेखा पर सही अंतराल कौन सा है?
If (x) is a real number and \(x\notin[2,5]\), which interval is correct on the number line?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,2\)\cup\(5,\infty\))
Concept
Since ([2,5]) includes (2) and (5), the outside part will not include them. Thus both boundaries are open.
Why this answer is correct
The correct answer is A. (\(-\infty,2\)\cup\(5,\infty\)). Since ([2,5]) includes (2) and (5), the outside part will not include them. Thus both boundaries are open.
Exam Tip
([2,5]) में (2) और (5) शामिल हैं इसलिए बाहर का भाग उन्हें शामिल नहीं करेगा। इसलिए दोनों सीमाएँ खुली रहेंगी।
