If (f:A\to B), (A={1,2,3}), (B={2,4,6,8}), and (f(x)=2x), what is the range of (f)?यदि (f:A\to B), (A={1,2,3}), (B={2,4,6,8}) और (f(x)=2x) हो, तो (f) का परिसर क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ({2,4,6})({2,4,6})
Putting (x=1,2,3) gives images (2,4,6). In exams, the range is only the set of actually obtained images.(x=1,2,3) रखने पर छवियां (2,4,6) मिलती हैं। परीक्षा में परिसर केवल प्राप्त छवियों का समुच्चय होता है।
