\(यदि हल ({x:x\le -4\) या \(x>5}) है तो interval notation क्या होगा\)?
\(If the solution is ({x:x\le -4\) or \(x>5}), what is the interval notation\)?
Explanation opens after your attempt
A. ((-\infty,-4]\cup\(5,\infty\))
Concept
\(\le -4\) gives a closed endpoint, and (>5) gives an open endpoint. In exams, always use round brackets on the infinite side.
Why this answer is correct
The correct answer is A. ((-\infty,-4]\cup\(5,\infty\)). \(\le -4\) gives a closed endpoint, and (>5) gives an open endpoint. In exams, always use round brackets on the infinite side.
Exam Tip
\(\le -4\) बंद endpoint देता है और (>5) खुला endpoint देता है। परीक्षा में infinite side पर हमेशा round bracket लगाएँ।
