यदि (f(x)=x-2-1) और (g(x)=x-2+1) हैं तो ((g-f)(x)) कौन सा फलन है?
If (f(x)=x-2-1) and (g(x)=x-2+1) then what type of function is ((g-f)(x))?
Explanation opens after your attempt
A. स्थिर फलनConstant function
Concept
((g-f)(x)=x-2+1-\(x^2-1\)=2), so it is a constant function. Equal highest-degree terms may cancel.
Why this answer is correct
The correct answer is A. स्थिर फलन / Constant function. ((g-f)(x)=x-2+1-\(x^2-1\)=2), so it is a constant function. Equal highest-degree terms may cancel.
Exam Tip
((g-f)(x)=x-2+1-\(x^2-1\)=2), इसलिए यह स्थिर फलन है। समान उच्च घात पद कट सकते हैं।
