A cosine function has a period of 5π/6, an amplitude of 6, and a vertical translation of 5 down. The function is not reflected over the x-axis. What is the equation for this cosine function?

 

Fill in the blanks using the following answer choices: -6, -5, 5, 6, 5π/5, 5/6, 5π/12, 12π/5, 12/5

cos (x)     not refelected    = cos (x)

Amplitude = 6      multiply the function by 6

Vertical translation DOWN 5      subtract   5 from the function

Period 5pi/6        2 pi / (5pi/6) = 12/5  x       for the object of the cos function
