Question

Let $$f:R \to R$$ be defined by
$$ f\left( x \right) = \left\{ {\begin{pmatrix} {k - 2x,\,\,if} & {x \le  - 1}  \
   {2x + 3,\,\,if} & {x >  - 1}  \ \end{pmatrix} } \right.$$

Accepted Answer

$$f\left( x \right) = \left\{ {\begin{pmatrix} {k - 2x,\,\,\,\,if\,\,\,\,x \le  - 1}  \
   {2x + 3,\,\,\,\,if\,\,\,\,x >  - 1}  \

\end{pmatrix} } \right.$$

This is true where $k=-1$
