\(यदि (A={x:x\in \mathbb{R}\) और \(-4<x\leq 1}) है, तो (A) का अंतराल रूप कौन-सा है\)?
\(If (A={x:x\in \mathbb{R}\) and \(-4<x\leq 1}), which is the interval form of (A)\)?
Explanation opens after your attempt
A. ((-4,1])open at (-4), closed at (1)
Concept
The condition (-4<x) shows that (-4) is not included.
Why this answer is correct
The condition \(x\leq 1\) shows that (1) is included.
Exam Tip
In exams, use a round bracket for an excluded endpoint and a square bracket for an included endpoint. चरण 1: शर्त (-4<x) बताती है कि (-4) शामिल नहीं है। चरण 2: शर्त \(x\leq 1\) बताती है कि (1) शामिल है। चरण 3: परीक्षा में खुले सिरे के लिए गोल कोष्ठक और शामिल सिरे के लिए वर्ग कोष्ठक लगाएँ।
