Determine If the Function Is a Power Function $$f ( x ) = 6 x ^ { - 3 / 4 }$$

Multiple Choice

Determine if the function is a power function. If it is, then state the power and constant of variation.
- $$f ( x ) = 6 x ^ { - 3 / 4 }$$

A) Power is $- \frac { 3 } { 4 } ;$ constant of variation is 6
B) Power is 6; constant of variation is $- \frac { 3 } { 4 }$
C) Power is $\frac { 3 } { 4 }$ ; constant of variation is 6
D) Not a power function
