Katerina Да, верно. не могу составить систему уравнений (((
Нужно исходить из того, что числитель дроби должен быть не равен нулю, а выражение под знаком радикала должно быть неотрицательным.

Изобразите на координатной плоскости штриховой линией параболу - график функции 
Заштрихуйте область, расположенную внутри параболы выше неё. Это и будет искомая область определения заданной функции.

Здравствуйте, Katerina!
Область определения заданной функции - часть координатной плоскости, расположенная выше параболы На рисунке она показана частично.
Это следует из того, что выражение под знаком радикала должно быть неотрицательным, а знаменатель дроби должен быть не равен нулю:
С уважением.
