यदि (f(x)=x-2) और (g(x)=x+1) हों, तो ((f-g)(0)) क्या होगा?
If (f(x)=x-2) and (g(x)=x+1), what is ((f-g)(0))?
Explanation opens after your attempt
A. (-1)
Concept
(f(0)=0) and (g(0)=1), so ((f-g)(0)=0-1=-1). At (0), do not forget the constant term.
Why this answer is correct
The correct answer is A. (-1). (f(0)=0) and (g(0)=1), so ((f-g)(0)=0-1=-1). At (0), do not forget the constant term.
Exam Tip
(f(0)=0) और (g(0)=1), इसलिए ((f-g)(0)=0-1=-1)। (0) पर value रखते समय constant term न भूलें।
