Determine If the Function Is a Power Function $$f ( x ) = \frac { 1 } { 3 } x ^ { 2 }$$

Multiple Choice

Determine if the function is a power function. If it is, then state the power and constant of variation.
- $$f ( x ) = \frac { 1 } { 3 } x ^ { 2 }$$

A) Power is 2; constant of variation is $\frac { 1 } { 3 }$
B) Power is 2; constant of variation is 2
C) Power is $\frac { 1 } { 3 } ;$ constant of variation is 2
D) Not a power function
