फलन (f(x)=x-2-6x+11) का परिसर क्या है, जब \(x\in[1,5]\)?

What is the range of (f(x)=x-2-6x+11) when \(x\in[1,5]\)?

Explanation opens after your attempt
Correct Answer

A. ( [2,6] )

Step 1

Concept

Since (f(x)=(x-3)2+2), the minimum is (2). At the endpoints (x=1) and (x=5), the maximum is (6).

Step 2

Why this answer is correct

The correct answer is A. ( [2,6] ). Since (f(x)=(x-3)2+2), the minimum is (2). At the endpoints (x=1) and (x=5), the maximum is (6).

Step 3

Exam Tip

(f(x)=(x-3)2+2), इसलिए न्यूनतम (2) है। सिरा (x=1) और (x=5) पर अधिकतम (6) मिलता है।
