Find the Domain x-y=5

Problem

x−y=5

Solution

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

y=x−5

2. Identify the type of function.

ƒ(x)=x−5

3. Analyze the function for restrictions. Since ƒ(x) is a linear polynomial, there are no values of x that would result in division by zero or the square root of a negative number.

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

Final Answer

Domain:(−∞,∞)
