If relation (R) is defined by (R={(x,y):y=2x,\ x\in{1,2,3}}), what can be the smallest codomain so that (R) is a function?यदि relation (R) को (R={(x,y):y=2x,\ x\in{1,2,3}}) से define किया गया है, तो (R) का codomain न्यूनतम कौन-सा हो सकता है ताकि (R) फलन बने?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \({2,4,6})\({2,4,6})
The outputs are (2,4,6), so the smallest codomain can be the set of these images. The codomain must contain all possible outputs.outputs (2,4,6) हैं, इसलिए smallest codomain इन्हीं images का set हो सकता है। codomain में सभी possible outputs होने चाहिए।
