यदि (f(x)=x-2), (g(x)=x) और (h(x)=1) हैं, तो ((f-2g+h)(x)) किसके बराबर है?
If (f(x)=x-2), (g(x)=x), and (h(x)=1), what is ((f-2g+h)(x))?
Explanation opens after your attempt
A. ((x-1)2)
Concept
(f-2g+h=x-2-2x+1=(x-1)2). In combinations of many functions, combine like terms step by step.
Why this answer is correct
The correct answer is A. ((x-1)2). (f-2g+h=x-2-2x+1=(x-1)2). In combinations of many functions, combine like terms step by step.
Exam Tip
(f-2g+h=x-2-2x+1=(x-1)2)। कई फलनों के संयोजन में समान पदों को क्रम से जोड़ें।
