Which is the correct representation of (x\notin[-6,2)) on the number line?संख्या रेखा पर (x\notin[-6,2)) का सही निरूपण कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((-\infty,-6)\cup[2,\infty))((-\infty,-6)\cup[2,\infty))
The given interval includes (-6) and excludes (2), so the complement excludes (-6) and includes (2). In exams, check endpoints carefully while taking complements.दिए गए interval में (-6) शामिल है और (2) शामिल नहीं है, इसलिए complement में (-6) हटेगा और (2) शामिल होगा। परीक्षा में complement लेते समय endpoints उलटकर जाँचें।
