question 171

Multiple Choice

Calculate the derivative of the function. Then find the value of the derivative as specified.
- $$f ( x ) = \frac { 8 } { x } ; f ^ { \prime } ( - 1 )$$

• A) \(\mathrm { f } ^ { \prime } ( \mathrm { x } ) = 8 ; \mathrm { f } ^ { \prime } ( - 1 ) = 8\)
• B) \(f ^ { \prime } ( x ) = \frac { 8 } { x ^ { 2 } } ; f ^ { \prime } ( - 1 ) = 8\)
• C) \(f ^ { \prime } ( x ) = - \frac { 8 } { x ^ { 2 } } ; f ^ { \prime } ( - 1 ) = - 8\)
• D) \(f ^ { \prime } ( x ) = - 8 x ^ { 2 } ; f ^ { \prime } ( - 1 ) = - 8\)
