यदि (f(x)=x-2+1) और (g(x)=2x-3) हैं, तो ((3f-2g)(x)) क्या है?
If (f(x)=x-2+1) and (g(x)=2x-3), what is ((3f-2g)(x))?
Explanation opens after your attempt
A. \(3x^2-4x+9\)
Concept
(3f-2g=3\(x^2+1\)-2(2x-3)=3x-2-4x+9). Apply the coefficient to the whole function.
Why this answer is correct
The correct answer is A. \(3x^2-4x+9\). (3f-2g=3\(x^2+1\)-2(2x-3)=3x-2-4x+9). Apply the coefficient to the whole function.
Exam Tip
(3f-2g=3\(x^2+1\)-2(2x-3)=3x-2-4x+9)। गुणांक को पूरे फलन पर लागू करें।
