[Solved] Find the indicated partial derivative. \[f ( x , y ) = x ^ { 2 } y ^ { 4 } - 3 x ^ { 4 } y , f _ { m x }\] A) \(f _ { xx x } = 12 x ^ { 2 } y\) B) \(f _ { xx x } = - 36 x y\) C) \(f _ { xx x } = 3 x y\) D) \(f _ { xxx } = - 72 x y\) E) \(f _ { xx x } = - 3 x y\) Current Assets: Assets that are expected to be converted into cash, sold, or consumed within one year or within the operating cycle of a business, whichever is longer.
