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
Correct Answer

A. ([-10,2])

Step 1

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.

Step 2

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.

Step 3

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।
