यदि (f(x)=x-2) और (g(x)=-x-2) हों, तो ((f+g)(x)) कौन सी function है?
If (f(x)=x-2) and (g(x)=-x-2), which function is ((f+g)(x))?
Explanation opens after your attempt
A. zero function (0)
Concept
((f+g)(x)=x-2-x-2=0), so it is the zero function. The sum of equal opposite functions gives zero.
Why this answer is correct
The correct answer is A. zero function (0). ((f+g)(x)=x-2-x-2=0), so it is the zero function. The sum of equal opposite functions gives zero.
Exam Tip
((f+g)(x)=x-2-x-2=0), इसलिए यह zero function है। समान opposite functions का sum zero देता है।
