Find the Domain 4x+y=18

Problem

4*x+y=18

Solution

1. Identify the type of equation. The equation 4*x+y=18 represents a linear function.

2. Solve for y to express the equation in slope-intercept form.

y=−4*x+18

3. Analyze the expression for restrictions. A linear function is a polynomial of degree 1. Polynomials are defined for all real numbers because there are no denominators that could be zero and no even-indexed roots of negative numbers.

4. Determine the domain. Since there are no values of x that make the expression undefined, the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
