यदि (x) वास्तविक संख्या है और \(x\notin(-1,4)\), तो सही संख्या रेखा निरूपण क्या है?
If (x) is a real number and \(x\notin(-1,4)\), what is the correct number line representation?
Explanation opens after your attempt
B. (\(-\infty,-1]\cup[4,\infty\))
Concept
((-1,4)) does not include (-1) and (4), so the complement includes both. Hence the outside regions have closed endpoints.
Why this answer is correct
The correct answer is B. (\(-\infty,-1]\cup[4,\infty\)). ((-1,4)) does not include (-1) and (4), so the complement includes both. Hence the outside regions have closed endpoints.
Exam Tip
((-1,4)) में (-1) और (4) शामिल नहीं हैं इसलिए पूरक में दोनों शामिल होंगे। अतः बाहरी भाग बंद सिरों के साथ होगा।
