If (f:A\to B) is a function and (A={2,4,6}), what will be the number of ordered pairs in (f)?यदि (f:A\to B) एक फलन है और (A={2,4,6}), तो (f) में ordered pairs की संख्या क्या होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3)(3)
In any function, the number of ordered pairs equals the number of elements in the domain. Here (|A|=3), so there are (3) pairs.किसी भी फलन में ordered pairs की संख्या domain के elements की संख्या के बराबर होती है। यहां (|A|=3), इसलिए pairs (3) हैं।
