Find the Domain X-y=3

Problem

x−y=3

Solution

1. Rewrite the equation in terms of y to express it as a function of x

y=x−3

2. Identify the type of function.

ƒ(x)=x−3

3. Analyze the expression for any restrictions. Since ƒ(x) is a linear polynomial, there are no square roots of negative numbers, no denominators that could be zero, and no logarithms.

4. Determine the domain. Because the function is defined for all real numbers, the domain is all real numbers.

Final Answer

Domain: *(−∞,∞)
