А) $f(x)=-16x-2\\f(x)\ \textgreater \ 0=\ \textgreater \ -16x-2\ \textgreater \ 0=\ \textgreater \ x\ \textless \ -\frac{1}{8}$
б) $f'(x)=x^{2}-2x\\f'(x)\ \textgreater \ 0=\ \textgreater \ x(x-2)\ \textgreater \ 0=\ \textgreater \ \left \[[ {{x\ \textgreater \ 2} \atop {x\ \textless \ 0}} \right.$
в) $f'(x)=1-12x\\f'(x)\ \textgreater \ 0=\ \textgreater \ 1-12x\ \textgreater \ 0=\ \textgreater \ x\ \textless \ \frac{1}{12}$
г) $f'(x)=-x^2-x\\f'(x)\ \textgreater \ 0=\ \textgreater \ -x(x+1)\ \textgreater \ 0=\ \textgreater \ -1\ \textless \ x\ \textless \ 0$
