The sum of all local minimum values of the function
$$f ( x ) = \left\{ \begin{array} { l r }
1 - 2 x , & x < - 1 \\
\frac { 1 } { 3 } ( 7 + 2 | x | ) , & - 1 \leq x \leq 2 \\
\frac { 11 } { 18 } ( x - 4 ) ( x - 5 ) , & x > 2
\end{array} \right.$$
is\\
(1) $\frac { 157 } { 72 }$\\
(2) $\frac { 131 } { 72 }$\\
(3) $\frac { 171 } { 72 }$\\
(4) $\frac { 167 } { 72 }$
