यदि (f(x)=x-2-4) और (g(x)=x-2+4) हैं, तो ((g-f)(x)) क्या होगा?
If (f(x)=x-2-4) and (g(x)=x-2+4), what is ((g-f)(x))?
Explanation opens after your attempt
A. (8)
Concept
((g-f)(x)=\(x^2+4\)-\(x^2-4\)=8). The like \(x^2\) terms cancel.
Why this answer is correct
The correct answer is A. (8). ((g-f)(x)=\(x^2+4\)-\(x^2-4\)=8). The like \(x^2\) terms cancel.
Exam Tip
((g-f)(x)=\(x^2+4\)-\(x^2-4\)=8)। समान \(x^2\) पद कट जाते हैं।
