यदि \(A=\{1,2,4,5\}\) और \(f:A\to\mathbb{R}\), (f(x)=\sqrt{x-1}) है, तो रेंज क्या है?
If \(A=\{1,2,4,5\}\) and \(f:A\to\mathbb{R}\), (f(x)=\sqrt{x-1}), what is the range?
Explanation opens after your attempt
A. \({0,1,\sqrt{3},2}\)
Concept
For (x=1,2,4,5), the outputs are \(0,1,\sqrt{3},2\). In exams use only the given inputs in a set domain.
Why this answer is correct
The correct answer is A. \({0,1,\sqrt{3},2}\). For (x=1,2,4,5), the outputs are \(0,1,\sqrt{3},2\). In exams use only the given inputs in a set domain.
Exam Tip
(x=1,2,4,5) पर outputs \(0,1,\sqrt{3},2\) मिलते हैं। परीक्षा में set domain में केवल दिए गए inputs लें।
