यदि (f(x)=2x+3), (g(x)=x-4) और (h(x)=x-2) हैं, तो ((f+g-h)(x)) क्या है?
If (f(x)=2x+3), (g(x)=x-4), and (h(x)=x-2), what is ((f+g-h)(x))?
Explanation opens after your attempt
A. \(-x^2+3x-1\)
Concept
((f+g-h)(x)=2x+3+x-4-x-2=-x-2+3x-1). With many functions, combine terms in order.
Why this answer is correct
The correct answer is A. \(-x^2+3x-1\). ((f+g-h)(x)=2x+3+x-4-x-2=-x-2+3x-1). With many functions, combine terms in order.
Exam Tip
((f+g-h)(x)=2x+3+x-4-x-2=-x-2+3x-1)। कई फलनों में पदों को क्रम से मिलाएँ।
