Find the Domain x-2y

Problem

x−2*y

Solution

1. Identify the type of expression given. The expression x−2*y is a linear polynomial in two variables, x and y

2. Determine if there are any restrictions on the variables. Restrictions typically occur with denominators (which cannot be zero), square roots of negative numbers, or logarithms of non-positive numbers.

3. Analyze the expression for these restrictions. Since x−2*y involves only subtraction and multiplication by constants, it is defined for all real values of x and y

4. State the domain in terms of the set of all possible ordered pairs (x,y)

Final Answer

Domain={(x,y)∈ℝ2}
