Ответ:
\[y = 0,5x^{2}\]
| \[x\] | \[0\] | \[1\] | \[2\] | \[- 1\] | \[- 2\] |
|---|---|---|---|---|---|
| \[y\] | \[0\] | \[0,5\] | \[2\] | \[0,5\] | \[2\] |

\[y( - 2) = 2\]
\[y(3) = 4,5\]
\[y(4) = 8\]
\[y = 0,5x^{2}\]
| \[x\] | \[0\] | \[1\] | \[2\] | \[- 1\] | \[- 2\] |
|---|---|---|---|---|---|
| \[y\] | \[0\] | \[0,5\] | \[2\] | \[0,5\] | \[2\] |

\[y( - 2) = 2\]
\[y(3) = 4,5\]
\[y(4) = 8\]
