If (A=[-2,5]) and (B=(1,7]), what is \(A\setminus B\)?
Explanation opens after your attempt
Correct Answer
A. ([-2,1])
Concept
Since (1) is not included in (B), elements after (1) are removed from (A), leaving ([-2,1]). In difference questions, check open and closed endpoints carefully.
Why this answer is correct
The correct answer is A. ([-2,1]). Since (1) is not included in (B), elements after (1) are removed from (A), leaving ([-2,1]). In difference questions, check open and closed endpoints carefully.
Exam Tip
(B) में (1) शामिल नहीं है, इसलिए (A) से (1) के बाद वाले तत्व हटेंगे और ([-2,1]) बचेगा। अंतर निकालते समय खुले और बंद सिरों पर ध्यान दें।
