If the representation of (x\le 3) is to be drawn, what mark is made at (3)?यदि (x\le 3) का निरूपण बनाना है तो (3) पर कौन सा चिन्ह बनेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Closed circleभरा वृत्त
In \(x\le 3\), \(x=3\) is included because \(3\le 3\) is true. Therefore, a closed circle is drawn at 3 on the number line. An open circle is used only when the boundary value is excluded, as in \(x<3\). Exam tip: use a closed circle for \(\le\) and \(\ge\), and an open circle for \(<\) and \(>\).असमानता \(x\le 3\) में \(x=3\) भी समाधान है, क्योंकि \(3\le 3\) सत्य है। इसलिए संख्या रेखा पर 3 पर भरा वृत्त बनाया जाता है। खाली वृत्त केवल तब बनता है जब सीमा मान शामिल न हो, जैसे \(x<3\)। परीक्षा टिप: \(\le\) और \(\ge\) के लिए भरा वृत्त, जबकि \(<\) और \(>\) के लिए खाली वृत्त बनाइए।
