यदि (f(x)=x-2-4x+4), (g(x)=x-2) और (h(x)=1) हैं, तो ((f-2gh)(x)) क्या है?
If (f(x)=x-2-4x+4), (g(x)=x-2), and (h(x)=1), what is ((f-2gh)(x))?
Explanation opens after your attempt
A. \(x^2-6x+8\)
Concept
(gh=x-2), so \(f-2gh=x^2-4x+4-2x+4=x^2-6x+8\). In combined functions, do multiplication first.
Why this answer is correct
The correct answer is A. \(x^2-6x+8\). (gh=x-2), so \(f-2gh=x^2-4x+4-2x+4=x^2-6x+8\). In combined functions, do multiplication first.
Exam Tip
(gh=x-2), इसलिए \(f-2gh=x^2-4x+4-2x+4=x^2-6x+8\)। संयुक्त फलनों में पहले गुणन करें।
