Answer

The domain of the function g(x, y) is {(x,y)yx22}

Steps

Step 1 :The function g(x, y) is defined for all real numbers except for those that make the denominator zero because division by zero is undefined in mathematics.

Step 2 :The denominator of the function g(x, y) is 4y2x2. Setting this equal to zero gives us the equation 4y2x2=0.

Step 3 :Solving this equation for y gives us y=x22.

Step 4 :Therefore, the domain of the function g(x, y) is all real numbers (x, y) except for those that satisfy the equation y=x22.

Step 5 :The domain of the function g(x, y) is {(x,y)yx22}
