यदि (f(x)=x-2) और डोमेन ([2,5]) है, तो रेंज क्या होगी?
If (f(x)=x-2) and the domain is ([2,5]), what is the range?
Explanation opens after your attempt
A. ([4,25])
Concept
On ([2,5]), \(x^2\) is increasing, so endpoint values are (4) and (25). In exams include endpoints for a closed interval.
Why this answer is correct
The correct answer is A. ([4,25]). On ([2,5]), \(x^2\) is increasing, so endpoint values are (4) and (25). In exams include endpoints for a closed interval.
Exam Tip
([2,5]) पर \(x^2\) बढ़ता है, इसलिए सिरों पर वैल्यू (4) और (25) मिलती हैं। परीक्षा में बंद अंतराल के endpoint शामिल करें।
