यदि (f(x)=x-2+1) है, तो ((f+f)(x)) क्या होगा?
If (f(x)=x-2+1), what is ((f+f)(x))?
Explanation opens after your attempt
A. \(2x^2+2\)
Concept
((f+f)(x)=2f(x)=2\(x^2+1\)=2x-2+2). Adding the same function gives (2f(x)).
Why this answer is correct
The correct answer is A. \(2x^2+2\). ((f+f)(x)=2f(x)=2\(x^2+1\)=2x-2+2). Adding the same function gives (2f(x)).
Exam Tip
((f+f)(x)=2f(x)=2\(x^2+1\)=2x-2+2)। समान फलन जोड़ने पर (2f(x)) बनता है।
