Составим таблицу значений функции $$y = x(x - 3.5)$$ для значений x от 0 до 4 с шагом 0.5.
| x | y = x(x - 3.5) |
|---|---|
| 0 | $$0(0 - 3.5) = 0$$ |
| 0.5 | $$0.5(0.5 - 3.5) = 0.5(-3) = -1.5$$ |
| 1 | $$1(1 - 3.5) = 1(-2.5) = -2.5$$ |
| 1.5 | $$1.5(1.5 - 3.5) = 1.5(-2) = -3$$ |
| 2 | $$2(2 - 3.5) = 2(-1.5) = -3$$ |
| 2.5 | $$2.5(2.5 - 3.5) = 2.5(-1) = -2.5$$ |
| 3 | $$3(3 - 3.5) = 3(-0.5) = -1.5$$ |
| 3.5 | $$3.5(3.5 - 3.5) = 3.5(0) = 0$$ |
| 4 | $$4(4 - 3.5) = 4(0.5) = 2$$ |
