यदि (A=[-4,2)\cup(5,9]) और (B=(-1,6]) हैं, तो \(A\setminus B\) क्या है?

If (A=[-4,2)\cup(5,9]) and (B=(-1,6]), what is \(A\setminus B\)?

Explanation opens after your attempt
Correct Answer

A. ([-4,-1]\cup(6,9])

Step 1

Concept

Since (B=(-1,6]) excludes (-1) and includes (6), removing it from (A) leaves ([-4,-1]\cup(6,9]). In differences, handle open and closed endpoints carefully.

Step 2

Why this answer is correct

The correct answer is A. ([-4,-1]\cup(6,9]). Since (B=(-1,6]) excludes (-1) and includes (6), removing it from (A) leaves ([-4,-1]\cup(6,9]). In differences, handle open and closed endpoints carefully.

Step 3

Exam Tip

(B=(-1,6]) में (-1) नहीं है और (6) शामिल है, इसलिए (A) से बीच का भाग हटकर ([-4,-1]\cup(6,9]) बचता है। अंतर में खुले-बंद सिरों पर विशेष ध्यान दें।
