यदि (f(x)=x-2-1) और (g(x)=x-2+1) हैं, तो ((g-f)(x)) का परिसर क्या है?

If (f(x)=x-2-1) and (g(x)=x-2+1), what is the range of ((g-f)(x))?

Explanation opens after your attempt
Correct Answer

A. ({2})

Step 1

Concept

((g-f)(x)=2), so its range is only ({2}). The range of a constant function is a singleton set.

Step 2

Why this answer is correct

The correct answer is A. ({2}). ((g-f)(x)=2), so its range is only ({2}). The range of a constant function is a singleton set.

Step 3

Exam Tip

((g-f)(x)=2), इसलिए इसका परिसर केवल ({2}) है। स्थिर फलन का परिसर एक-सदस्यीय होता है।
