यदि (A=[-4,6)) और (B=(-1,8]) हैं, तो \(A\setminus B\) क्या है?
If (A=[-4,6)) and (B=(-1,8]), what is \(A\setminus B\)?
Explanation opens after your attempt
Correct Answer
A. ([-4,-1])
Concept
The point (-1) is not included in (B), so the part of (A) up to (-1) remains. Check open and closed endpoints separately in interval difference.
Why this answer is correct
The correct answer is A. ([-4,-1]). The point (-1) is not included in (B), so the part of (A) up to (-1) remains. Check open and closed endpoints separately in interval difference.
Exam Tip
(B) में (-1) शामिल नहीं है, इसलिए (A) का (-1) तक का भाग बचता है। अंतर निकालते समय खुले और बंद सिरों को अलग से जाँचें।
