Ответ:
\[y = \frac{x^{2} + x^{3}}{x + 1}\]
\[x + 1 \neq 0\]
\[x \neq - 1\]

\[y = x²\]
| \[x\] | \[- 2\] | \[- 1\] | \[0\] | \[1\] | \[2\] |
|---|---|---|---|---|---|
| \[y\] | \[4\] | \[-\] | \[0\] | \[1\] | \[4\] |

\[y = \frac{x^{2} + x^{3}}{x + 1}\]
\[x + 1 \neq 0\]
\[x \neq - 1\]

\[y = x²\]
| \[x\] | \[- 2\] | \[- 1\] | \[0\] | \[1\] | \[2\] |
|---|---|---|---|---|---|
| \[y\] | \[4\] | \[-\] | \[0\] | \[1\] | \[4\] |
