Answer:
All real numbers.
Explanation:
The domain of a function is the set of all possible input values (also called the independent variable) for which the function is defined. In other words, it is the set of all values of x for which the function f(x) produces a valid output (also called the dependent variable). The domain of a function can be described using a variety of notations, including interval notation, set notation, or inequalities.
For example, if we consider the function f(x) = 1/x, we know that the denominator cannot be equal to zero, so the domain of this function is all real numbers except x = 0. Therefore, the domain of f(x) is:
Domain of f(x) = (-∞, 0) U (0, ∞)
It is important to determine the domain of a function before attempting to evaluate it or manipulate it algebraically, as the function may produce undefined or meaningless results for certain input values outside of its domain.
Additionally, the graph is drawn for each actual number.
Hence any real integers larger than or equal to -2 fall inside the function's range.
The answer is all real numbers.
