कौन सा विकल्प \(x\in\mathbb{R}\) और (x<0) को दर्शाता है?
Which option represents \(x\in\mathbb{R}\) and (x<0)?
Explanation opens after your attempt
A. (\(-\infty,0\))
Concept
(x<0) includes all negative real numbers and does not include (0). Therefore (\(-\infty,0\)) is correct.
Why this answer is correct
The correct answer is A. (\(-\infty,0\)). (x<0) includes all negative real numbers and does not include (0). Therefore (\(-\infty,0\)) is correct.
Exam Tip
(x<0) में सभी ऋणात्मक वास्तविक संख्याएं आती हैं और (0) शामिल नहीं होता। इसलिए (\(-\infty,0\)) सही है।
