A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 9, the vertical shift is 11 units down, and the period of the function is 12π7. The graph of the function does not show a phase shift.

 

What is the equation of the cosine function described?

Correctly complete the equation of the function.

f(x)= __cos( __ x ) __
