Determine If the Function Is a Power Function $$f ( x ) = - \frac { 3 } { 4 } x ^ { 5 }$$

Multiple Choice

Determine if the function is a power function. If it is, then state the power and constant of variation.
- $$f ( x ) = - \frac { 3 } { 4 } x ^ { 5 }$$

A) Not a power function
B) Power is 5; constant of variation is $- \frac { 3 } { 4 }$
C) Power is $\frac { 3 } { 4 }$ ; constant of variation is 5
D) Power is 5; constant of variation is $\frac { 3 } { 4 }$
