Find the Domain -x-y=-2

Problem

−x−y=−2

Solution

1. Identify the type of equation. The equation −x−y=−2 is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Solve for y to express the equation in function form.

−y=x−2

y=−x+2

3. Analyze the resulting function ƒ(x)=−x+2 This is a polynomial function of degree 1.

4. Determine the restrictions. Polynomial functions are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

5. Conclude that the domain consists of all real numbers.

Final Answer

Domain: *(−∞,∞)
