Понятие квадратного корня из неотрицательного числа

• Квадратным корнем из неотрицательного числа a называют такое неотрицательное число, квадрат которого равен a . Это число обозначают √ a , число при этом называют подкоренным числом.

Определения

• Операцию нахождения квадратного корня из неотрицательного числа называют извлечением квадратного корня. Эта операция является обратной по отношению к возведению в квадрат. Например, 5 2 =25 и √25=5.

Используем следующую таблицу для построения графика функции

X 0

Y 0

Построим найденные точки (0;0), (1;1), (4;2), (6,25;2,5) , (9;3) , (16;4)

в координатной плоскости. Они располагаются на некоторой

линии, начертим ее. Получили график функции y= √x.

График функции квадратного корня

0 при х 0 . 3. Функция непрерывна на луче [ 0 ;+∞) . 4. Функция ограничена снизу и не ограничена сверху. 5. у наим =0 (достигается при х=0), у наиб не существует. " width="640"

Функция квадратного корня

• Свойства функции y= √ x :
• 1. Область определения функции – луч [ 0 ;+∞) .
• 2. у=0 при х=0 ; у 0 при х 0 .
• 3. Функция непрерывна на луче [ 0 ;+∞) .
• 4. Функция ограничена снизу и не ограничена сверху.
• 5. у наим =0 (достигается при х=0), у наиб не существует.

Свойства квадратных корней

Математический диктант

• Учитель предлагает учащимся плакат с утверждениями, некоторые из которых содержат ошибки или неточности. Учащиеся должны

• определить верные и неверные утверждения. Свой ответ они должны аргументировать, ссылаясь на известные свойства и правила.
