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