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

\[y( - 10) = - \frac{1}{2}\]
\[y( - 2) = - 2,5\]
\[y(5) = 1\]
\[y = \frac{5}{x}\]
| \[x\] | \[1\] | \[5\] | \[2\] | \[0\] | \[- 1\] | \[- 5\] | \[- 2\] |
|---|---|---|---|---|---|---|---|
| \[y\] | \[5\] | \[1\] | \[2,5\] | \[-\] | \[- 5\] | \[- 1\] | \[- 2,5\] |

\[y( - 10) = - \frac{1}{2}\]
\[y( - 2) = - 2,5\]
\[y(5) = 1\]
