Provide an Appropriate Response $f ( t ) = k a^ t$

Multiple Choice

Provide an appropriate response.
-Use the properties of exponents to write the function of the form $f ( t ) = k a^ t$ , where $k$ is a constant. $f ( t ) = \left( \frac { 1 } { 3 } \right) ^ { 2 - 3 t }$

A) $f ( t ) = \frac { 1 } { 9 } \left( \frac { 1 } { 27 } \right) ^ t$
B) $f ( t ) = \left( \frac { 1 } { 27 } \right) 9^ t$
C) $f ( t ) = 9 \cdot 27 ^t$
D) $f ( t ) = \left( \frac { 1 } { 9 } \right) 27 ^t$
