Для проверки принадлежности точки (16-4√7; √14 - √2) графику функции y =√x нужно подставить значение координаты x точки в функцию и проверить, равна ли полученная в результате выражения координата y точке.

Таким образом, подставляя x = 16-4√7 в y =√x, получим:

y = √(16-4√7) ≈ 2.83

Подставляя значение координаты y точки (16-4√7; √14 - √2) в полученное выражение, получаем:

√14 - √2 ≈ 2.38

Таким образом, координата y точки не равна значению функции y = √x в точке x = 16-4√7, следовательно, точка (16-4√7; √14 - √2) не принадлежит графику функции y =√x.
