Find $\small{f(5), f(-2), f(\pi ), \;\mbox{and}\; f(-2.1)}$ for :

$$\small{f(x) = \begin{cases}\displaystyle{\sqrt{x+2}}&\text{if}\ x > 2\cr \displaystyle{1}&\text{if}\ x \le 2\end{cases}}$$

You may keep radicals in any answers where appropriate. Use pi to represent $\small{\pi}$.

$\small{f(5)}$	=
$\small{f(-2)}$	=
$\small{f(\pi )}$	=
$\small{f(-2.1)}$	=
