यदि \(A=\{1,2,3\}\), \(B=\{2,4,8\}\) और (f(x)=2^x) हो, तो (f) का परिसर क्या है?
If \(A=\{1,2,3\}\), \(B=\{2,4,8\}\), and (f(x)=2^x), what is the range of (f)?
Explanation opens after your attempt
Correct Answer
B. ({2,4,8})
Concept
\(2^1=2\), \(2^2=4\), and \(2^3=8\), so the range is ({2,4,8}). In exams, substitute every input in an exponential rule.
Why this answer is correct
The correct answer is B. ({2,4,8}). \(2^1=2\), \(2^2=4\), and \(2^3=8\), so the range is ({2,4,8}). In exams, substitute every input in an exponential rule.
Exam Tip
\(2^1=2\), \(2^2=4\) और \(2^3=8\), इसलिए परिसर ({2,4,8}) है। परीक्षा में घातीय नियम में हर इनपुट रखें।
