Find the Domain y=-x-1

Problem

y=−x−1

Solution

1. Identify the type of function. The given equation y=−x−1 is a linear function.

2. Analyze the expression for restrictions. A domain is restricted if there are denominators that could be zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Determine the possible values for x Since there are no fractions, roots, or logarithms, the variable x can be any real number.

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

Final Answer

Domain: *(−∞,∞)
