Final answer:
The domain of a vector function represents the set of all possible input values.
Step-by-step explanation:
The domain of a vector function represents the set of all possible input values. In other words, it is the set of all permissible values for the independent variable(s) of the function.
For a vector function, the domain is typically determined by the restrictions on the independent variable(s) given in the problem or context. It could be a specific interval, a set of discrete values, or even all real numbers or integers, depending on the situation.
Therefore, the correct answer for the domain of a vector function would be c) Set of all real numbers or d) Set of all integers, depending on the specific problem.
