Answer:

As below.

Explanation:

Standard form of equation is #y = A cos (Bx -C) + D#

Given equation is #y = -5 cos theta - 5#

#A = -5, B = 1, C = 0, D = -5#

#"Amplitude " = |A| = 5#

#"Period " = (2pi) / |B| = 2pi#

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

#"Vertical Shift " = D = -5#

graph{(-5) cos (x) - 5 [-10.67, 9.33, -6.92, 3.08]}
