Problem 24

Question

Describe the region \(R\) in the \(x y\) -plane that corresponds to the domain of the function. $$ g(x, y)=\frac{1}{x-y} $$

Step-by-Step Solution

Verified
Answer
The domain of the function is all points (x, y) in xy-plane except those points where x = y.
1Step 1: Understand the Domain of a Function
Domain is defined as the set of all possible values of x that can be put into the given function without violating any mathematical rules. In this function, x can be any real number except when x = y.
2Step 2: Define the Expression for Domain
In the function g(x, y) = 1/(x-y), domain is undefined where x-y equals zero or simply x = y. Therefore, the domain of the function g is all set of points (x, y) in the xy-plane except those points where x = y.
3Step 3: Graph Representation
This domain can be represented graphically as the xy-plane excluding the line y = x.
