As below.

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

$Given : y = - 5 cos 6 x$ $"Given : " y = -5 cos 6x$

$A = - 5, B = 6, C = D = 0$ $A = -5, B = 6, C = D = 0$

$Amplitude = | A | = | - 5 | = 5$ $"Amplitude " = |A| = |-5| = 5$

$Period = \frac{2 π}{| B |} = \frac{2 π}{6} = \frac{π}{3}$ $"Period " = (2 pi) / |B| = (2 pi) / 6 = pi/3$

$Phase Shift = - \frac{C}{B} = 0$ $"Phase Shift " = -C / B = 0$

$"Vertical Shift ' = D = 0$
