यदि (f(x)=2x+3) और (g(x)=x-2-1) हों, तो ((f+g)(x)) क्या होगा?
If (f(x)=2x+3) and (g(x)=x-2-1), what is ((f+g)(x))?
Explanation opens after your attempt
A. \(x^2+2x+2\)
Concept
((f+g)(x)=f(x)+g(x)), so \(2x+3+x^2-1=x^2+2x+2\). In exams, combine like terms carefully.
Why this answer is correct
The correct answer is A. \(x^2+2x+2\). ((f+g)(x)=f(x)+g(x)), so \(2x+3+x^2-1=x^2+2x+2\). In exams, combine like terms carefully.
Exam Tip
((f+g)(x)=f(x)+g(x)), इसलिए \(2x+3+x^2-1=x^2+2x+2\)। परीक्षा में like terms को साथ जोड़ें।
