Find the Domain -x+4y=4

Problem

−x+4*y=4

Solution

1. Identify the type of equation. The given equation −x+4*y=4 is a linear equation in two variables.

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

4*y=x+4

y=1/4*x+1

3. Analyze the resulting function ƒ(x)=1/4*x+1 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 can be zero and no even roots of negative numbers.

5. Conclude that the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
