यदि \(U=\mathbb{R}\) और (A=[-1,4]), तो \(A^{c}\) क्या है?
If \(U=\mathbb{R}\) and (A=[-1,4]), what is \(A^{c}\)?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,-1\)\cup\(4,\infty\))
Concept
([-1,4]) includes the endpoints, so the complement does not include them. The complement of a closed interval has open endpoints.
Why this answer is correct
The correct answer is A. (\(-\infty,-1\)\cup\(4,\infty\)). ([-1,4]) includes the endpoints, so the complement does not include them. The complement of a closed interval has open endpoints.
Exam Tip
([-1,4]) में अंतिम बिंदु शामिल हैं, इसलिए पूरक में वे शामिल नहीं होंगे। बंद अंतराल का पूरक खुले अंतिम बिंदु देता है।
