а)Координаты пересечения параболой оси Ох (-2; 0); (2; 0)
б)Координаты пересечения параболой оси Оу (0; 12)
Объяснение:
Найти координаты точек пересечения параболы
y=-3x²+12 с осями координат.
а)Чтобы найти точки пересечения параболы с осью Ох, нужно решить квадратное уравнение:
-3x²+12=0
3x²-12=0
х₁,₂=±√144/6
х₁,₂=±12/6
х₁= -2
х₂=2
Координаты пересечения параболой оси Ох (-2; 0); (2; 0)
б)Любой график пересекает ось Оу при х=0.
х=0
y= -3x²+12
у=0+12
у=12
Координаты пересечения параболой оси Оу (0; 12)
