यदि (f(x)=-3x+2) और डोमेन ([0,4]) है, तो रेंज क्या होगी?
If (f(x)=-3x+2) and the domain is ([0,4]), what is the range?
Explanation opens after your attempt
A. ([-10,2])
Concept
The function is decreasing, so at (x=0) it gives (2) and at (x=4) it gives (-10). In exams the order may reverse for a decreasing function.
Why this answer is correct
The correct answer is A. ([-10,2]). The function is decreasing, so at (x=0) it gives (2) and at (x=4) it gives (-10). In exams the order may reverse for a decreasing function.
Exam Tip
फलन घटता है, इसलिए (x=0) पर (2) और (x=4) पर (-10) मिलता है। परीक्षा में घटते फलन में क्रम बदल सकता है।
