Цель урока — научиться строить график квадратичной функции (т.е. параболу), а затем с помощью графика проводить элементарное исследование квадратичной функции.

Задач, в которых так или иначе фигурирует парабола, великое множество. Это одна из тем, которые будут преследовать вас до самого конца школы.

Ключевые навыки, которые мы сегодня отработаем:
1. Собственно, строить параболу и определять: лежит ли на ней точка с указанными координатами или не лежит;
2. Определять, где функция возрастает, а где убывает;
3. Искать наибольшее и наименьшее значение квадратичной функции на заданном отрезке;
4. Наконец, отработаем графическое решение уравнений и систем, в которых фигурируют линейные и квадратичные функции

1 этап -- древняя Греция -- возникновение науки в социуме с провозглашением геометрии, как науки об измерении земли.
- работали не с реальными предметами, не с эмпирическим объектом, а с математическими моделями -- абстракциями.
- из всех понятий выводились аксиома и опираясь на них с помощью логического обоснования выводили новые понятия.
2 этап -- Средневековая европейская наука -- наука превратилась в служанку богословия. Противоборство между номиналистами (единичные вещи) и реалистами (универсальные вещи).
