Model the Curve with a Cosine Function $P = \frac { 1 } { 5 }$

Multiple Choice

Model the curve with a cosine function.
Note that the period of the curve is $P = \frac { 1 } { 5 }$ , its range is $[ - 3.3,3.3 ]$ and the graph of the cosine function is shifted to the right 0.35 units.

A) $f ( x ) = 6.6 \cos ( 20 \pi ( 2 x - 0.35 ) )$
B) $f ( x ) = 3.3 \cos ( 10 ( x - 0.35 ) )$
C) $f ( x ) = 6.6 \cos ( 20 \pi ( 2 x + 0.35 ) )$
D) $f ( x ) = 3.3 \cos ( 10 \pi ( x - 0.35 ) )$
E) $f ( x ) = 3.3 \cos ( 10 \pi ( x + 0.35 ) )$
