यदि \(f:A\to B\) फलन है और \(C\subseteq A\), तो (f(C)) के बारे में कौन सा कथन हमेशा सत्य है?
If \(f:A\to B\) is a function and \(C\subseteq A\), which statement about (f(C)) is always true?
Explanation opens after your attempt
A. \(f(C)\subseteq B\)
Concept
All elements of (C) lie in (A), and their images lie in the codomain (B). Hence \(f(C)\subseteq B\) is always true.
Why this answer is correct
The correct answer is A. \(f(C)\subseteq B\). All elements of (C) lie in (A), and their images lie in the codomain (B). Hence \(f(C)\subseteq B\) is always true.
Exam Tip
(C) के सभी अवयव (A) में हैं और उनकी छवियां सहप्रांत (B) में होती हैं। इसलिए \(f(C)\subseteq B\) हमेशा सत्य है।
