फलन (f(x)=\sqrt{2x-x-2}+3) का परिसर क्या है?

What is the range of (f(x)=\sqrt{2x-x-2}+3)?

Explanation opens after your attempt
Correct Answer

A. ( [3,4] )

Step 1

Concept

Since (2x-x-2=1-(x-1)2), its value lies from (0) to (1). After square root and adding (3), the range is ([3,4]).

Step 2

Why this answer is correct

The correct answer is A. ( [3,4] ). Since (2x-x-2=1-(x-1)2), its value lies from (0) to (1). After square root and adding (3), the range is ([3,4]).

Step 3

Exam Tip

(2x-x-2=1-(x-1)2), जिसका मान (0) से (1) तक है। वर्गमूल के बाद (3) जोड़ने से परिसर ([3,4]) है।
