Find the Domain x-y=25

Problem

x−y=25

Solution

1. Identify the type of equation. The equation x−y=25 represents a linear function.

2. Solve for y to express the equation in function notation y=ƒ(x)

y=x−25

3. Analyze the expression for restrictions. The expression x−25 is a polynomial. Polynomials are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

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

Final Answer

Domain: *(−∞,∞)
