A simple proof is given for the fact that for
$m$ a non-negative integer, a function
$f\,\in \,{{C}^{(m)}}\,(\mathbb{R})$, and an arbitrary positive continuous function
$\in$, there is an entire function
$g$ such that
$\left| {{g}^{(i)}}(x)\,-\,{{f}^{(i)}}(x) \right|\,<\,\in (x)$, for all
$x\,\in \,\mathbb{R}$ and for each
$i\,=\,0,\,1\,.\,.\,.\,,\,m$. We also consider the situation where
$\mathbb{R}$ is replaced by an open interval.
