Mathematics - Functions Question with Solution | TestHub

If function f satisfies the relation $\mathrm{f}(\mathrm{x}).{\mathrm{f}}^{\prime }(-\mathrm{x})=\mathrm{f}(-\mathrm{x}).{\mathrm{f}}^{\prime }(\mathrm{x})$ for all x and $\mathrm{f}(0)=3$, now if $\mathrm{f}(3)=$ 3 , then the value of f(-3) is
