If \(g(x)\) is the inverse of the function \(f(x)\) and \(f^{\prime}(x)=\frac{1}{h(x)}\), then \(g^{\prime}(x)=\)
- A \(h(g(x))\)
- B \(\mathrm{g}(\mathrm{h}(\mathrm{x}))\)
- C \(h^{\prime}(f(x))\)
- D \(f(h(x))\)
Answer & Solution
Correct Answer
(A) \(h(g(x))\)
Step-by-step Solution
Detailed explanation
Given \(g(x)\) is inverse of the function \(f(x) \& f^{\prime}(x)\) \(=\frac{1}{\mathrm{~h}(\mathrm{x})}\) Now, \(g(x)=f^{-1}(x) \Rightarrow f(g(x))=x\) Differentiating w.r. to \(x\).…
