Find the Domain (x+y)=15

Problem

x+y=15

Solution

1. Identify the type of equation provided. The equation x+y=15 represents a linear function in two variables, which can be rewritten in slope-intercept form as y=15−x

2. Determine if there are any restrictions on the input variable x In a linear polynomial expression, there are no denominators that could be zero and no even-indexed roots (like square roots) containing the variable.

3. Conclude that since the expression is defined for all real numbers, the domain consists of all real values of x

Final Answer

Domain:(−∞,∞)
