Explanation Given: Function f ( x , y ) = x 2 y . Formula Used: Formula of second-order partial derivatives are as follows: ∂ 2 f ∂ x 2 = f x x = ( f x ) x ∂ 2 f ∂ y 2 = f y y = ( f y ) y ∂ 2 f ∂ x ∂ y = f y x = ( f y ) x ∂ 2 f ∂ y ∂ x = f x y = ( f x ) y Calculation: Function is given as f ( x , y ) = x 2 y . Differentiate f ( x , y ) with respect to x , we get ∂ f ∂ x = ∂ ∂ x ( x 2 y ) f x = y ∂ ∂ x ( x 2 ) f x = y ( 2 x ) f x = 2 x y Differentiate f ( x , y ) with respect to y , we get ∂ f ∂ y = ∂ ∂ y ( x 2 y ) f y = x 2 ∂ ∂ y ( y ) f y = x 2 ( 1 ) f y = x 2 Now, ∂ 2 f ∂ x 2 = f x x = ( f x ) x f x x = ∂ ∂ x ( 2 x y ) f x x = 2 y ∂ ∂</
