    y = -5 - 3*cos(3x).      ANSWER.



EXPLANATION


    The minimum value of -8 and the amplitude of 3 dictate that the midline is y = -5.


    The fact that the minimum is at x= 0 dictates to use the cosine function flipped/reflected about the midline.


    The argument of  (3x)  provides / models the period  .
