Ответ:
\[y = \left\{ \begin{matrix} x - 3,\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x \geq 0 \\ - 2x - 3,\ \ x < 0 \\ \end{matrix} \right.\ \]
\[y = x - 3\]
| \[x\] | \[0\] | \[1\] |
|---|---|---|
| \[y\] | \[- 3\] | \[- 2\] |
\[y = - 2x - 3\]
| \[x\] | \[0\] | \[- 1\] |
|---|---|---|
| \[y\] | \[- 3\] | \[- 1\] |
