Multiple Choice

Find the domain of f(x,y) =xx2y2f ( x , y ) = \frac { x } { x ^ { 2 } - y ^ { 2 } }


A) Dom(f) ={(x,y) R2:xy}\operatorname { Dom } ( f ) = \left\{ ( x , y ) \in R ^ { 2 } : x \neq y \right\}
B) Dom(f) ={(x,y) R2:xy}\operatorname { Dom } ( f ) = \left\{ ( x , y ) \in R ^ { 2 } : x \neq - y \right\}
C) Dom(f) ={(x,y) R2:xy}\operatorname { Dom } ( f ) = \left\{ ( x , y ) \in R ^ { 2 } : | x | \neq | y | \right\}
D) Dom(f) =R2\operatorname { Dom } ( f ) = R ^ { 2 }
