यदि (f(x)=x-2+4x+4) और (g(x)=x+2) हैं, तो (\left\(\frac{f}{g}\right\)(-2)) के बारे में सही कथन कौन सा है?
If (f(x)=x-2+4x+4) and (g(x)=x+2), which statement about (\left\(\frac{f}{g}\right\)(-2)) is correct?
Explanation opens after your attempt
A. अपरिभाषित हैIt is undefined
Concept
(\frac{f}{g}=\frac{(x+2)2}{x+2}), but at (x=-2) the original denominator is (0). Cancellation does not bring that point back into the domain.
Why this answer is correct
The correct answer is A. अपरिभाषित है / It is undefined. (\frac{f}{g}=\frac{(x+2)2}{x+2}), but at (x=-2) the original denominator is (0). Cancellation does not bring that point back into the domain.
Exam Tip
(\frac{f}{g}=\frac{(x+2)2}{x+2}) है, पर (x=-2) पर मूल हर (0) है। कटाव के बाद भी वह बिंदु प्रांत में वापस नहीं आता।
