Пошаговое объяснение:
1) Построим график функции.
Графиком функции является парабола, ветви вверх.
Парабола пересекает Ох в точках (1; 0) и (7; 0)
График приведен на рисунке.
По поводу неравенства:
Неравенство нестрогое - поэтому граничные точки включаются в решение. На графике видно, что неравенству удовлетворяют те части параболы, которые находятся НАД осью Ох. Включая и сами точки, в которых значенте функции равно нулю.
На рисунке часть графика НЕ удовлетворяющая неравенству обозначена красным.
Синий цвет графика - решение неравенства. Как видно, это 2 промежутка:
