Find the Domain (sn)=(n-2)

Problem

s(n)=n−2

Solution

1. Identify the type of function provided. The expression s(n)=n−2 is a linear polynomial function.

2. Determine if there are any mathematical restrictions. For polynomial functions, there are no denominators that could be zero and no even-indexed roots (like square roots) that could contain negative values.

3. Conclude the domain based on the lack of restrictions. Since the expression n−2 is defined for all real numbers, the domain consists of all possible values of n

Final Answer

Domain: *(−∞,∞)
