If (f:R\to R), (f(x)=x^3), what is (f^{-1}(x))?यदि (f:R\to R), (f(x)=x^3), तो (f^{-1}(x)) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\sqrt[3]{x})(\sqrt[3]{x})
Step 1: Write (y=x^3). Step 2: Then (x=\sqrt[3]{y}). Step 3: 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})।
