यदि \(f:{1,2,3,4}\to{1,2}\) को (f(x)=1) जब (x<2) और (f(x)=2) जब \(x\ge 2\) से परिभाषित किया गया है, तो (f(2)) क्या है?
If \(f:{1,2,3,4}\to{1,2}\) is defined by (f(x)=1) when (x<2) and (f(x)=2) when \(x\ge 2\), what is (f(2))?
Explanation opens after your attempt
Correct Answer
B. (2)
Concept
Because \(2\ge 2\), (f(2)=2). In exams, check which condition contains the boundary point.
Why this answer is correct
The correct answer is B. (2). Because \(2\ge 2\), (f(2)=2). In exams, check which condition contains the boundary point.
Exam Tip
क्योंकि \(2\ge 2\), इसलिए (f(2)=2) है। परीक्षा में सीमा बिंदु किस शर्त में आता है यह जांचें।
