Find the Domain x-y=-5

Problem

x−y=−5

Solution

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

y=x+5

2. Identify the type of function.
   The equation y=x+5 is a linear function.

3. Determine any restrictions on the input variable x
   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. State the domain in interval notation.
   Since there are no restrictions, the domain consists of all real numbers.

Domain=(−∞,∞)

Final Answer

Domain of *x−y=−5* is *(−∞,∞)
