Final answer:
The domain of a two-variable function f(x, y) is R x R, which means x and y can be any real number. Domain of two-variable function f(x, y) is all real numbers for x and y: Domain = R x R.
Step-by-step explanation:
The domain of a function refers to the set of all possible values for the independent variable(s) in the function. In this case, the function f(x, y) is a two-variable function. To find the domain, we need to determine the values of x and y that are allowed in the function.
Step 1:
Examine any restrictions on the variables. In the given information, there are no restrictions mentioned, so we can assume that x and y can take any real number value.
Step 2:
Write the domain in interval notation. Since both x and y can take any real number value, the domain can be represented as:
Domain = R x R
This means that x and y can be any real number.
