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 !
