Level I
If $a, b \in R^{+}$and for all $x$ in $R, f(a+x)=b+\left[b^{3}\right.$ $\left.+1-3 b^{2} f(x)+3 b\{f(x)\}^{2}-\{f(x)\}^{3}\right]^{1 / 3}$. Prove that $f(x)$ is periodic.
Level III
Let $f: R^{+} \rightarrow R$ satisfies the functional equation $f(x y)=e^{x y-x-y}\left(e^{y} f(x)+e^{x} f(y)\right) \forall x, y \in R^{+} .$ If $f^{\prime}(1)=e$, determine $f(x)$
