Find the Domain x-y=4

Problem

x−y=4

Solution

1. Identify the type of equation provided. The equation x−y=4 represents a linear function, which can be rewritten in slope-intercept form as y=x−4

2. Determine if there are any restrictions on the input variable x In a linear polynomial function, there are no square roots of negative numbers, no logarithms of non-positive numbers, and no denominators that could equal zero.

3. Conclude the domain based on the lack of restrictions. Since x can be any real number without making the expression undefined, the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
