question 32

Multiple Choice

Model the curve with a cosine function.
Note that the period of the curve is $P = 14$ , its range is $[ 0,120 ]$ the graph of the cosine function is shifted upward 60 units and shifted to the right 7 units.

• A) \(f ( x ) = 120 \cos \left( \frac { \pi ( x - 60 ) } { 60 } \right) + 7\)
• B) \(f ( x ) = 120 \cos \left( \frac { \pi ( x - 60 ) } { 60 } \right) - 7\)
• C) \(f ( x ) = 60 \cos \left( \frac { \pi ( x + 7 ) } { 7 } \right) + 60\)
• D) \(f ( x ) = 7 \cos \left( \frac { \pi ( x - 60 ) } { 60 } \right) + 7\)
• E) \(f ( x ) = 60 \cos \left( \frac { \pi ( x - 7 ) } { 7 } \right) + 60\)
