Find the Domain f(n)=2n-1

Problem

ƒ(n)=2*n−1

Solution

1. Identify the type of function. The expression 2*n−1 is a linear polynomial function.

2. Check for restrictions. Polynomial functions do not contain divisions by zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Determine the set of possible input values. Since there are no mathematical constraints on the variable n the function is defined for all real numbers.

4. Express the domain in interval notation. The set of all real numbers is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
