Find the Domain x=-2y-8

Problem

x=−2*y−8

Solution

1. Identify the independent and dependent variables. In the equation x=−2*y−8 x is expressed as a function of y To find the domain of the relation where y is the independent variable, we examine the restrictions on y

2. Analyze the expression for any restrictions such as division by zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Determine that the expression −2*y−8 is a linear polynomial. Polynomials are defined for all real numbers.

4. Conclude that there are no values of y that make the expression undefined. Therefore, the domain consists of all real numbers.

Final Answer

Domain: *(−∞,∞)
