यदि (f(x)=x-2) और (g(x)=2x+1) हैं, तो ((f+g)(-2)) का मान क्या है?
If (f(x)=x-2) and (g(x)=2x+1), what is the value of ((f+g)(-2))?
Explanation opens after your attempt
A. (1)
Concept
((f+g)(-2)=f(-2)+g(-2)=4+(-3)=1). Finding values separately reduces errors.
Why this answer is correct
The correct answer is A. (1). ((f+g)(-2)=f(-2)+g(-2)=4+(-3)=1). Finding values separately reduces errors.
Exam Tip
((f+g)(-2)=f(-2)+g(-2)=4+(-3)=1)। पहले अलग-अलग मान निकालना गलती कम करता है।
