As below

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

Given $y = cos (x-pi) - 3$

$A = 1, B = 1, C = pi, D = -3$

$Amplitude = |A| = 1$

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

$"Phase Shift " = -C / B = pi, " " pi " to the right"$

$"Vertical Shift " = D = -3, " 3 down"$

graph{cos(x - pi) - 3 [-10, 10, -5, 5]}
