Consider the function f ( x , y ) = 2 x + 3 y x 2 y .

(a) Find the domain of f ( x , y ) .

(b) Evaluate f ( 4 ,   12 ) .

(a)

To determine

To calculate: The domain of the function f(x,y)=2x+3yx2y.

Explanation

Given Information:

The provided function is f(x,y)=2x+3yx2y.

Formula used:

The domain of a function of two variables f(x,y) is the set of all ordered pairs (x,y) for which the function is well-defined.

If the function maps each element of the domain to an element in the codomain, then it is said to be well defined.

To find the domain of a rational function, set the denominator of the function equals to zero. Then the domain of the function is the set of all ordered pairs except the values for which the denominator is zero.

The function f(x)=x is defined for all x0.

Calculation:

Consider the function, f(x,y)=2x+3yx2y.

The function f(x,y) is a rational function.

Recall that, to find the domain of a rational function, set the denominator of the function equals to zero. Then the domain of the function is the set of all ordered pairs except the values for which the denominator is zero.

The denominator of the function f(x,y)=2x+3yx2y is x2y

(b)

To determine

To calculate: The value of f(4,12) for the function f(x,y)=2x+3yx2y.
