Пример квадратичной функции, график которой касается прямой
y = 5 в точке с абсциссой -2.
график функции 2 y x bx c = ++ проходит через точки ( 2; 4) и (3; 1).
а) найдите коэффициент b.
б) постройте график на координатной плоскости.
на окружности с центом o отмечены точки a, b и c. отрезок ab —
диаметр окружности, ac = 4, bc = 2 5 . найдите oc .
