फलन (f(x)=\frac{2x-3}{x+4}) के लिए कौन सा मान परिसर में नहीं आएगा?
Which value will not occur in the range of (f(x)=\frac{2x-3}{x+4})?
Explanation opens after your attempt
Correct Answer
A. (2)
Concept
From \(y=\frac{2x-3}{x+4}\), \(x=\frac{-3-4y}{y-2}\), so (y=2) is impossible. In such fractions, the ratio of leading coefficients often gives the missing value.
Why this answer is correct
The correct answer is A. (2). From \(y=\frac{2x-3}{x+4}\), \(x=\frac{-3-4y}{y-2}\), so (y=2) is impossible. In such fractions, the ratio of leading coefficients often gives the missing value.
Exam Tip
\(y=\frac{2x-3}{x+4}\) से \(x=\frac{-3-4y}{y-2}\), इसलिए (y=2) असंभव है। अनुपात में प्रमुख गुणांकों का अनुपात अक्सर छूटा मान देता है।
