Find the Domain y=-x-4

Problem

y=−x−4

Solution

1. Identify the type of function. The given equation y=−x−4 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions on the input variable x Polynomial functions do not contain square roots of negative numbers, logarithms, or variables in the denominator.

3. Conclude that since there are no values of x that would make the expression undefined, 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: *(−∞,∞)
