यदि संख्या रेखा पर (2) और (9) के बीच छायांकन है, (2) बंद और (9) खुला है, तो असमता रूप क्या होगा?
If the number line is shaded between (2) and (9), with (2) closed and (9) open, what is the inequality form?
Explanation opens after your attempt
D. \(2\le x<9\)
Concept
The closed endpoint includes (2), and the open endpoint excludes (9). Therefore the correct inequality is \(2\le x<9\).
Why this answer is correct
The correct answer is D. \(2\le x<9\). The closed endpoint includes (2), and the open endpoint excludes (9). Therefore the correct inequality is \(2\le x<9\).
Exam Tip
बंद सिरा (2) को शामिल करता है और खुला सिरा (9) को बाहर रखता है। इसलिए सही असमता \(2\le x<9\) है।
