Find the Domain 2x-y=0

Problem

2*x−y=0

Solution

1. Identify the type of equation. The equation 2*x−y=0 is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Solve for y to express the relation as a function of x

y=2*x

3. Analyze the function for restrictions. A linear function of the form ƒ(x)=m*x+b is defined for all real numbers because there are no denominators that could be zero and no square roots of negative numbers.

4. Determine the domain. Since x can take any real value, the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
