If (f:A \to \mathbb{R}) and (R={(x,y):f(x)\le f(y)}), what is (R)?यदि (f:A \to \mathbb{R}) और (R={(x,y):f(x)\le f(y)}) हो, तो (R) कैसा होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Reflexiveस्ववाची
Step 1: For reflexivity, put (x=y). Step 2: (f(x)\le f(x)) is true for every (x). Step 3: The function need not be increasing or decreasing for this.चरण 1: स्ववाचीता के लिए (x=y) रखें। चरण 2: (f(x)\le f(x)) हर (x) के लिए सत्य है। चरण 3: यहाँ फलन का बढ़ना या घटना जरूरी नहीं है।
