यदि (f(x)=3x+2) है और ((f+g)(x)=x-2+3x+5) है तो (g(x)) क्या होगा?
If (f(x)=3x+2) and ((f+g)(x)=x-2+3x+5) then what is (g(x))?
Explanation opens after your attempt
A. \(x^2+3\)
Concept
(g(x)=(f+g)(x)-f(x)=x-2+3x+5-(3x+2)=x-2+3). To find the unknown function subtract the known function from the given sum.
Why this answer is correct
The correct answer is A. \(x^2+3\). (g(x)=(f+g)(x)-f(x)=x-2+3x+5-(3x+2)=x-2+3). To find the unknown function subtract the known function from the given sum.
Exam Tip
(g(x)=(f+g)(x)-f(x)=x-2+3x+5-(3x+2)=x-2+3)। अज्ञात फलन निकालने के लिए दिए गए योग से ज्ञात फलन घटाएँ।
