Пошаговое объяснение:
х2-21+54=0
таперь находим дискрименант: D=21^2-54*4=441-216=225/
21-15
теперь находим корни: х1==3
2
21+15
х2==18
2
теперь находим среднее арифметическое: 18+3
=10,5
2
ответ: среднее арифметическое 10,5.
Пошаговое объяснение:
ДАНО: Y = √(x²-2*x)
РЕШЕНИЕ
Под корнем должно быть не отрицательное число.
Решаем квадратное уравнение.
Корни: х = 0 и Y=0 и х = 2. Положительная функция при х >2
D(y) = [0];[2;+∞) - область определения функции.
Интервала уменьшения нет.
Возрастает при х = [2;+∞) - ответ
