यदि संख्या रेखा पर (-7) और (3) पर भरे वृत्त हैं तथा बाहर की ओर छायांकन है, तो निरूपण कौन सा है?
If the number line has closed circles at (-7) and (3) with outward shading, which representation is correct?
Explanation opens after your attempt
B. \(x\le -7\) या \(x\ge 3\)\(x\le -7\) or \(x\ge 3\)
Concept
Closed circles include both endpoints and outward shading shows two outside regions. So inclusive inequalities with or are used.
Why this answer is correct
The correct answer is B. \(x\le -7\) या \(x\ge 3\) / \(x\le -7\) or \(x\ge 3\). Closed circles include both endpoints and outward shading shows two outside regions. So inclusive inequalities with or are used.
Exam Tip
भरे वृत्त दोनों सीमाओं को शामिल करते हैं और बाहर की छायांकन दो बाहरी क्षेत्रों को दिखाती है। इसलिए बराबरी सहित या का प्रयोग होगा।
