Ответ:
\[y = - 2x²\]
| \[x\] | \[0\] | \[1\] | \[- 1\] | \[2\] | \[- 2\] |
|---|---|---|---|---|---|
| \[y\] | \[0\] | \[- 2\] | \[- 2\] | \[- 8\] | \[- 8\] |

\[y < 2\]
\[- 2x^{2} < - 2\]
\[x^{2} > 1\]
\[(x - 1)(x + 1) > 0\]

\[y = - 2x²\]
| \[x\] | \[0\] | \[1\] | \[- 1\] | \[2\] | \[- 2\] |
|---|---|---|---|---|---|
| \[y\] | \[0\] | \[- 2\] | \[- 2\] | \[- 8\] | \[- 8\] |

\[y < 2\]
\[- 2x^{2} < - 2\]
\[x^{2} > 1\]
\[(x - 1)(x + 1) > 0\]
