यदि (f(x)=2x-2-3) और (g(x)=x-2+5) हों, तो ((f-g)(x)) क्या होगा?
If (f(x)=2x-2-3) and (g(x)=x-2+5), what is ((f-g)(x))?
Explanation opens after your attempt
A. \(x^2-8\)
Concept
((f-g)(x)=2x-2-3-\(x^2+5\)=x-2-8). The whole (g(x)) is subtracted.
Why this answer is correct
The correct answer is A. \(x^2-8\). ((f-g)(x)=2x-2-3-\(x^2+5\)=x-2-8). The whole (g(x)) is subtracted.
Exam Tip
((f-g)(x)=2x-2-3-\(x^2+5\)=x-2-8)। पूरा (g(x)) घटाया जाता है।
