Ответ:
Подставляем каждое значение x в формулы. Например, при x = −3: 1/x = −1/3, −3/x = 1, 2/x = −2/3.
| Функция \ x | −3 | −2 | −1 | −1/2 | −1/3 | 1/3 | 1/2 | 1 | 2 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|
| y = 1/x | −1/3 | −1/2 | −1 | −2 | −3 | 3 | 2 | 1 | 1/2 | 1/3 |
| y = −3/x | 1 | 3/2 | 3 | 6 | 9 | −9 | −6 | −3 | −3/2 | −1 |
| y = 2/x | −2/3 | −1 | −2 | −4 | −6 | 6 | 4 | 2 | 1 | 2/3 |
