यदि (f(x)=\frac{5x+1}{2}), तो (f^{-1}(x)) क्या होगा?
If (f(x)=\frac{5x+1}{2}), what is (f^{-1}(x))?
Explanation opens after your attempt
A. \(\frac{2x-1}{5}\)
Concept
Write \(y=\frac{5x+1}{2}\).
Why this answer is correct
Then (2y=5x+1), so \(x=\frac{2y-1}{5}\).
Exam Tip
Replacing (y) by (x), (f^{-1}(x)=\frac{2x-1}{5}). चरण 1: \(y=\frac{5x+1}{2}\) लिखें। चरण 2: (2y=5x+1), इसलिए \(x=\frac{2y-1}{5}\)। चरण 3: (y) को (x) से बदलने पर (f^{-1}(x)=\frac{2x-1}{5})।
