Автор ответа: 1999lola

у(х)=3х^2+2x
Как известно нули функции это точки в которых график функции пересечётся с осями: Ох и Оу и для нахождения нулей нашей функции мы просто прировняем функцию к нулю и решим неполное квадратное уравнение:
3x^2+2x=0
x(3x+2)=0
x1=0 или 3х+2=0
3х=-2
х=-23
Ответ: (0;-23)
