Answer:
Step-by-step explanation:
Options a and d are right.
The given function is of the above form
[tex]y=acosb(x-p)+k[/tex]
We have here a=1/4 :b=1 : p = -pi/3: and k=-1
Hence we have an amplitude of 1/4, horizontal shift of pi/3 to the right,vertical shift of 1 unit down and vertical shrink of 1/4
Hence the correct choices would be
1) It has amplitude 1/4
d) Horizontal shift of pi/3 to the left
Other options are false
