यदि (f(x)=x-2-16) और (g(x)=x+4) हैं, तो \(x \neq -4\) के लिए (\left\(\frac{f}{g}\right\)(-1)) का मान क्या है?
If (f(x)=x-2-16) and (g(x)=x+4), what is (\left\(\frac{f}{g}\right\)(-1)) for \(x \neq -4\)?
Explanation opens after your attempt
A. (3)
Concept
(\left\(\frac{f}{g}\right\)(x)=\frac{(x-4)(x+4)}{x+4}=x-4), so at (x=-1) the value is (-5). Check directly as \(\frac{-15}{3}=-5\).
Why this answer is correct
The correct answer is A. (3). (\left\(\frac{f}{g}\right\)(x)=\frac{(x-4)(x+4)}{x+4}=x-4), so at (x=-1) the value is (-5). Check directly as \(\frac{-15}{3}=-5\).
Exam Tip
(\left\(\frac{f}{g}\right\)(x)=\frac{(x-4)(x+4)}{x+4}=x-4), इसलिए (x=-1) पर मान (-5) होना चाहिए; पर सही जाँच में \(\frac{-15}{3}=-5\)।
