यदि \(f:A\to B\), \(A=\{0,1,2,3\}\), \(B=\{1,3,5,7,9\}\) और (f(x)=2x+1), तो range क्या है?
If \(f:A\to B\), \(A=\{0,1,2,3\}\), \(B=\{1,3,5,7,9\}\), and (f(x)=2x+1), what is the range?
Correct answer and explanation
A. \({1,3,5,7})
Simple Explanation
(x=0,1,2,3) रखने पर outputs (1,3,5,7) मिलते हैं। range हमेशा actual images का set होता है, पूरा codomain जरूरी नहीं। / Putting (x=0,1,2,3) gives outputs (1,3,5,7). The range is the set of actual images, not necessarily the whole codomain.
