यदि (f(x)=\sqrt{x-1}) और डोमेन ([1,10]) है, तो रेंज क्या होगी?
If (f(x)=\sqrt{x-1}) and the domain is ([1,10]), what is the range?
Explanation opens after your attempt
A. ([0,3])
Concept
\(\sqrt{x-1}\) is increasing, so endpoint values are (0) and (3). In exams include endpoints of a closed interval.
Why this answer is correct
The correct answer is A. ([0,3]). \(\sqrt{x-1}\) is increasing, so endpoint values are (0) and (3). In exams include endpoints of a closed interval.
Exam Tip
\(\sqrt{x-1}\) बढ़ता है, इसलिए endpoints पर वैल्यू (0) और (3) हैं। परीक्षा में बंद अंतराल के endpoints शामिल करें।
