यदि (f(x)=x-2) और डोमेन ([-7,-3]) है, तो रेंज क्या होगी?
If (f(x)=x-2) and the domain is ([-7,-3]), what is the range?
Explanation opens after your attempt
A. ([9,49])
Concept
On the negative interval, the smallest value of \(x^2\) is (9) and the largest is (49). In exams check endpoints when (0) is not in the interval.
Why this answer is correct
The correct answer is A. ([9,49]). On the negative interval, the smallest value of \(x^2\) is (9) and the largest is (49). In exams check endpoints when (0) is not in the interval.
Exam Tip
ऋणात्मक अंतराल पर \(x^2\) की सबसे छोटी वैल्यू (9) और सबसे बड़ी (49) है। परीक्षा में interval में (0) न हो तो endpoints जांचें।
