यदि (f(x)=3x-2) और ((f+g)(x)=x-2+x) है, तो (g(x)) क्या होगा?
If (f(x)=3x-2) and ((f+g)(x)=x-2+x), what is (g(x))?
Explanation opens after your attempt
A. \(x^2-2x+2\)
Concept
(g=(f+g)-f=x-2+x-(3x-2)=x-2-2x+2). To find the unknown function, subtract the whole known function.
Why this answer is correct
The correct answer is A. \(x^2-2x+2\). (g=(f+g)-f=x-2+x-(3x-2)=x-2-2x+2). To find the unknown function, subtract the whole known function.
Exam Tip
(g=(f+g)-f=x-2+x-(3x-2)=x-2-2x+2)। अज्ञात फलन निकालते समय पूरे फलन को घटाएं।
