Question

Область определения функции y = 14-2 x

Answer 1

Область определения все действительные числа, т.е. вместо х можно подставить любое число и значение функции будет иметь смысл.

Ответ: D(y)=(–б;+б)

Answer 2

y = 14 - 2x - Линейная функция

D(y) = (-∞; ∞)

Answer 3

The domain of a function is the set of all possible input values (x-values) for which the function is defined. In this case, the function is given as:

y = 14 - 2x

To find the domain of this function, we need to identify the values of x for which the function is defined. Since there are no specific restrictions mentioned in the function, it is assumed that the function is defined for all real numbers.

Therefore, the domain of the function y = 14 - 2x is all real numbers, which can be denoted as:

Domain: (-∞, +∞)
