Answer 2

It seems there might be a formatting error in your input. It's not clear what the function is, as you listed a series of numbers (1, 2, 3, 4, 5, 6) without any indication of the function itself. The term "область определения функции" translates to "domain of the function" in English.

In mathematics, the domain of a function is the set of all possible input values (or independent variables) for which the function is defined. Without knowing the specific function, I cannot determine its domain.

Could you please provide the function or clarify the question? Once I have the function, I'll be able to help you find its domain.
