Give an Appropriate Answer $$f ( x , y ) = 3 x - 3 y ^ { 2 } - 8$$

Multiple Choice

Give an appropriate answer.
- $$f ( x , y ) = 3 x - 3 y ^ { 2 } - 8$$

A) $\frac { \partial f } { \partial x } = - 5 ; \frac { \partial f } { \partial y } = - 6 y - 8$
B) $\frac { \partial f } { \partial x } = 3 x ; \frac { \partial f } { \partial y } = - 6 y$
C) $\frac { \partial f } { \partial x } = 3 ; \frac { \partial f } { \partial y } = - 6 y$
D) $\frac { \partial f } { \partial x } = - 6 y ; \frac { \partial f } { \partial y } = 3$
