यदि (f(x)=x-2+2) और (g(x)=2x-2-1) हों, तो ((g-f)(x)) क्या होगा?
If (f(x)=x-2+2) and (g(x)=2x-2-1), what is ((g-f)(x))?
Explanation opens after your attempt
A. \(x^2-3\)
Concept
((g-f)(x)=2x-2-1-\(x^2+2\)=x-2-3). Changing the order can change the subtraction result.
Why this answer is correct
The correct answer is A. \(x^2-3\). ((g-f)(x)=2x-2-1-\(x^2+2\)=x-2-3). Changing the order can change the subtraction result.
Exam Tip
((g-f)(x)=2x-2-1-\(x^2+2\)=x-2-3)। क्रम बदलने से घटाव का उत्तर बदल सकता है।
