So I have literally no idea how to even begin this problem and would greatly appreciate some help :)

Thanks in advance!

cos fxn is shifted UP to midline 8       so   r = 8

Amplitude is multiplied by 4                so m = 4

period is changed from 2pi to 8     so n :     8n=2pi      n= 2pi/8 = pi/4

 phase shifted by one to the RIGHT      so p = 1

 

f(x) = 4 cos(pi/4(x-1)) +8        you should finish from here !
