If (R={(1,2),(2,3),(3,4)), (A={1,2,3}), and (B={2,3,4,5}), which statement is correct?यदि (R={(1,2),(2,3),(3,4)}), (A={1,2,3}), और (B={2,3,4,5}) है तो सही कथन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R) is a function from (A) to (B)(R) (A) से (B) में फलन है
The elements (1), (2), and (3) of (A) each have exactly one image in (B). It is not necessary to use every element of the codomain.(A) के (1), (2), और (3) का ठीक एक प्रतिबिंब (B) में है। सहप्रांत के हर तत्व का प्रयोग होना जरूरी नहीं।
