यदि (f(x)=\frac{3x-2}{4}), तो (f^{-1}(x)) क्या होगा?
If (f(x)=\frac{3x-2}{4}), what is (f^{-1}(x))?
Explanation opens after your attempt
A. \(\frac{4x+2}{3}\)
Concept
Write \(y=\frac{3x-2}{4}\).
Why this answer is correct
Then (4y=3x-2), so \(x=\frac{4y+2}{3}\).
Exam Tip
Replacing (y) by (x), (f^{-1}(x)=\frac{4x+2}{3}). चरण 1: \(y=\frac{3x-2}{4}\) लिखें। चरण 2: (4y=3x-2), इसलिए \(x=\frac{4y+2}{3}\)। चरण 3: (y) को (x) से बदलने पर (f^{-1}(x)=\frac{4x+2}{3})।
