There is a part of the function
\[
f(x)=\left\{\begin{matrix}
&(x+6)^{-2}+2& x \in (-\infty;-5)\setminus\{-6\} \\
&3, & x \in [ -5;-3 ] \\
&1, & x \in (-3;-1) \\
&|x-1|-1& x \in [ -1,\infty)\setminus \{6\}\\
\end{matrix}\right.
\]
in the picture. Use the graph to determine at how many points of the given interval \([ -8; 7 ]\) is the function \(f\) defined and is not differentiable.
