If (f(x)=\frac{2x+3}{x-4}), which value is not in the range of (f)?यदि (f(x)=\frac{2x+3}{x-4}) है तो कौन सा मान (f) के परिसर में नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2)(2)
From (y=\frac{2x+3}{x-4}), we get (x=\frac{4y+3}{y-2}), so (y\ne2). In such questions find the unavailable (y).(y=\frac{2x+3}{x-4}) से (x=\frac{4y+3}{y-2}) मिलता है इसलिए (y\ne2)। ऐसे प्रश्न में अनुपलब्ध (y) खोजें।
