Explanation It is given that an function is f ( x , y ) = 4 x y 3 − y 2 . Substitute the values x = − 4 , y = 1 in the function and obtain the value f ( − 4 , 1 ) as follows. f ( − 4 , 1 ) = 4 ( − 4 ) ( 1 ) 3 − ( 1 ) 2 = − 16 − 1 = − 17 That is, f ( − 4 , 1 ) = − 17 . Substitute the values x = 1 , y = − 2 in the function and obtain the value f ( 1 , − 2 ) as follows
