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 सही मान क्या है?
If (f(x)=x-2-16) and (g(x)=x+4), what is the correct value of (\left\(\frac{f}{g}\right\)(-1)) for \(x \neq -4\)?
Explanation opens after your attempt
A. (-5)
Concept
(\frac{x-2-16}{x+4}=\frac{(x-4)(x+4)}{x+4}=x-4), hence (-1-4=-5). Substitute carefully after simplification.
Why this answer is correct
The correct answer is A. (-5). (\frac{x-2-16}{x+4}=\frac{(x-4)(x+4)}{x+4}=x-4), hence (-1-4=-5). Substitute carefully after simplification.
Exam Tip
(\frac{x-2-16}{x+4}=\frac{(x-4)(x+4)}{x+4}=x-4), अतः (-1-4=-5)। सरलीकरण के बाद सही मान रखें।
