\[\left\{ \begin{matrix} y = \frac{4}{x}\text{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ } \\ y = |x + 1| - 4 \\ \end{matrix} \right.\ \]

\[y = \frac{4}{x}\]

\[x\]	\[1\]	\[2\]	\[4\]	\[- 1\]	\[- 2\]	\[- 4\]
\[y\]	\[4\]	\[2\]	\[1\]	\[- 4\]	\[- 2\]	\[- 1\]

\[y = |x + 1| - 4\]

\[x\]	\[1\]	\[- 3\]	\[- 1\]
\[y\]	\[- 2\]	\[- 2\]	\[- 4\]

\[Ответ:( - 1;\ - 4);\ \ ( - 4;\ - 1);\ \ \]

\[(4;1).\]
