Find the Domain c=7x-3y

Problem

c=7*x−3*y

Solution

1. Identify the type of function provided. The expression c=7*x−3*y represents a linear function of two variables, x and y

2. Check for restrictions such as denominators that could be zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Determine that there are no such restrictions in this polynomial expression, meaning x and y can be any real numbers.

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

Final Answer

Domain={(x,y)|x∈ℝ,y∈ℝ}
