If (A={1,2,3}), (B={p,q,r}), and (R={(1,p),(2,q),(2,r),(3,p)}), why is (R) not a function?यदि (A={1,2,3}), (B={p,q,r}) और (R={(1,p),(2,q),(2,r),(3,p)}) हो, तो (R) फलन क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because (2) has two different imagesक्योंकि (2) की दो अलग छवियां हैं
(2) is associated with both (q) and (r), so it is not a function. In exams, check different images of a repeated first component.(2) को (q) और (r) दोनों से जोड़ा गया है, इसलिए यह फलन नहीं है। परीक्षा में दोहराए पहले घटक की अलग छवियां देखें।
