फलन \(f:{1,2,3,4}\to\mathbb{N}\) को (f(x)=\frac{12}{x}) से परिभाषित किया गया है। कौन सा कथन सही है?
The function \(f:{1,2,3,4}\to\mathbb{N}\) is defined by (f(x)=\frac{12}{x}). Which statement is correct?
Explanation opens after your attempt
B. यह फलन है और परिसर ({3,4,6,12}) हैIt is a function and range is ({3,4,6,12})
Concept
For each given (x), \(\frac{12}{x}\) is a natural number. The obtained values are ({12,6,4,3}).
Why this answer is correct
The correct answer is B. यह फलन है और परिसर ({3,4,6,12}) है / It is a function and range is ({3,4,6,12}). For each given (x), \(\frac{12}{x}\) is a natural number. The obtained values are ({12,6,4,3}).
Exam Tip
प्रत्येक दिए गए (x) के लिए \(\frac{12}{x}\) प्राकृतिक संख्या है। प्राप्त मान ({12,6,4,3}) हैं।
