As below.

$y = 4 cos x + 4$ $y = 4 cos x + 4$

Standard form of cosine function is $y = A cos (B x - C) + D$ $y = A cos (Bx - C) + D$

$A = 4, B = 1, C = 0, D = 4$ $A = 4, B = 1, C = 0, D = 4$

$Amplitude = | A | = 4$ $"Amplitude " = |A| = 4$

$"Period ' = (2pi) / |B| = 2pi$

$"Phase Shift = -C / B = 0$

$"Vertical Shift " = D = 4$
