Find the Domain x-y=10

Problem

x−y=10

Solution

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

y=x−10

2. Identify the type of function.
   The equation y=x−10 is a linear function.

3. Determine any restrictions on the input variable x
   In a linear function, there are no square roots of negative numbers or divisions by zero.

4. Conclude the domain.
   Since there are no restrictions, x can be any real number.

Final Answer

Domain: *(−∞,∞)
