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

\[y( - 1) = - 2\]
\[y( - 1,5) = - 4,5\]
\[y(2) = - 8\]
\[y = - 2x²\]
| \[x\] | \[0\] | \[1\] | \[- 1\] | \[2\] | \[- 2\] |
|---|---|---|---|---|---|
| \[y\] | \[0\] | \[- 2\] | \[- 2\] | \[- 8\] | \[- 8\] |

\[y( - 1) = - 2\]
\[y( - 1,5) = - 4,5\]
\[y(2) = - 8\]
