Question 85

Multiple Choice

Find the first partial derivative for the function f(x,y,z) =5x2y3xyz+6yz2 with f ( x , y , z ) = 5 x ^ { 2 } y - 3 x y z + 6 y z ^ { 2 } \text { with } respect to z.


A) fz(x,y,z) =3xz+9yzf _ { z } ( x , y , z ) = - 3 x z + 9 y z
B) fz(x,y,z) =6xy+12yzf _ { z } ( x , y , z ) = - 6 x y + 12 y z
C) fz(x,y,z) =12xy+15yzf _ { z } ( x , y , z ) = 12 x y + 15 y z
D) fz(x,y,z) =3xz+12yzf _ { z } ( x , y , z ) = 3 x z + 12 y z
E) fz(x,y,z) =3xy+12yzf _ { z } ( x , y , z ) = - 3 x y + 12 y z
