यदि \(f:A\to B\) आच्छादी है और \(B=\{2,4,6,8\}\), तो (f(A)) क्या होगा?
If \(f:A\to B\) is onto and \(B=\{2,4,6,8\}\), what is (f(A))?
Explanation opens after your attempt
A. \({2,4,6,8}\)
Concept
(f(A)) is the range of the function.
Why this answer is correct
If a function is onto, its range equals its codomain.
Exam Tip
Hence (f(A)=B={2,4,6,8}). चरण 1: (f(A)) फलन का परास है। चरण 2: आच्छादी होने पर परास सहप्रांत के बराबर होता है। चरण 3: इसलिए (f(A)=B={2,4,6,8})।
