\(यदि (R={x:x\) एक पूर्णांक है और \(-4<x\leq -1}) है, तो (R) का सूची रूप क्या है\)?
\(If (R={x:x\) is an integer and \(-4<x\leq -1}), what is the roster form of (R)\)?
Explanation opens after your attempt
A. \(R=\{-3,-2,-1\}\)
Concept
Because (-4<x), (-4) is not included.
Why this answer is correct
Because \(x\leq -1\), (-1) is included, so the elements are (-3,-2,-1).
Exam Tip
Read inequality signs carefully even with negative limits. चरण 1: (-4<x) के कारण (-4) शामिल नहीं है। चरण 2: \(x\leq -1\) के कारण (-1) शामिल है, इसलिए अवयव (-3,-2,-1) हैं। चरण 3: ऋणात्मक सीमाओं में भी असमानता चिह्नों को ध्यान से पढ़ें।
