Find the Domain x-2y=2

Problem

x−2*y=2

Solution

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

2. Solve for y in terms of x to express the equation as a function.

−2*y=−x+2

y=1/2*x−1

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

4. Determine the constraints. Since there are no denominators containing x no square roots of negative numbers, and no logarithms, the variable x can take any real value.

5. State the domain in interval notation. The domain of any non-vertical linear function is the set of all real numbers.

Final Answer

Domain:(−∞,∞)
