Aug 13, 2016

$k \left(- 6\right) = - 4$

#### Explanation:

$k \left(n\right) = n + 2$

or

$k \left(- 6\right) = - 6 + 2$

or
$k \left(- 6\right) = - 4$

$k \left(- 6\right) = - 4$

#### Explanation:

All the fancy notation just means that $n = - 6$
Replace $n$ by the value $- 6$

$k \left(\textcolor{red}{n}\right) = \textcolor{red}{n} + 2$

$\therefore k \left(\textcolor{red}{- 6}\right) = \textcolor{red}{- 6} + 2 = - 4$
