Mathematics - Application of Derivative Question with Solution | TestHub

Let $\mathrm{f}(\mathrm{x})$ be a positive differentiable function on [0,a]such that $\mathrm{f}(\mathrm{O})=1$ and $\mathrm{f}(\mathrm{a})=3^{1/4}$ If ${\mathrm{f}}^1(\mathrm{x})\ge (\mathrm{f}(\mathrm{x}){)}^3+(\mathrm{f}(\mathrm{x}){)}^{-1}$, then, maximum value of a is
