Question 51
Multiple Choice
Calculate ∂x∂f , ∂y∂f , and ∂z∂f when defined. f(x,y,z) =−x+y+z22
A) ∂x∂f=−(x+y+z2) 22 , ∂y∂f=−(x+y+z2) 22 , ∂z∂f=2z(x+y+z2) 22
B) ∂x∂f=x+y+z22 , ∂y∂f=x+y+z22 , ∂z∂f=x+y+z24z
C) ∂x∂f=(x+y+z2) 22 , ∂y∂f=(x+y+z2) 22 , ∂z∂f=(x+y+z2) 24z
D) ∂x∂f=(x+y+z2) 22x , ∂y∂f=(x+y+z2) 22y , ∂z∂f=(x+y+z2) 24z
E) ∂x∂f=(x+y+z2) 22 , ∂y∂f=(x+y+z2) 22 , ∂z∂f=(x+y+z) 24z
