Таблица значений:
| x | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 |
|---|---|---|---|---|---|---|---|---|
| y | -2 | -1 | 0 | 0 | +1 | +2 | +3 | +2 |
Решение:
Для построения графика необходимо отметить точки с координатами (x; y) на координатной плоскости и соединить их.
1. Отмечаем точки: \((0; -2), (2; -1), (4; 0), (6; 0), (8; 1), (10; 2), (12; 3), (14; 2)\).
2. Соединяем полученные точки последовательно отрезками.
Ответ: График представляет собой ломаную линию, проходящую через указанные точки.
