असमानता \(0\le x<\frac{9}{4}\) में संख्या रेखा पर कौन-से endpoints होंगे?
In the inequality \(0\le x<\frac{9}{4}\) what endpoints appear on the number line?
Explanation opens after your attempt
B. (0) बंद और \(\frac{9}{4}\) खुला(0) closed and \(\frac{9}{4}\) open
Concept
There is equality at (0) so it is closed and no equality at \(\frac{9}{4}\) so it is open. In exams draw mixed endpoints carefully.
Why this answer is correct
The correct answer is B. (0) बंद और \(\frac{9}{4}\) खुला / (0) closed and \(\frac{9}{4}\) open. There is equality at (0) so it is closed and no equality at \(\frac{9}{4}\) so it is open. In exams draw mixed endpoints carefully.
Exam Tip
(0) पर बराबरी है इसलिए बंद बिंदु और \(\frac{9}{4}\) पर बराबरी नहीं है इसलिए खुला बिंदु होगा। परीक्षा में mixed endpoints को ध्यान से बनाएं।
