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
