As below.

Explanation:

#y = - 2 sec (2x + 2pi) + 3#

Standard form of secant function is #y = A sec(Bx - C) + D#

#A = -2, B = 2, C = -2pi, D = 3#

#Amplitude = |A| = "None for secant function"#

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

#"Phase Shift " = -C/B = (2pi) / 2 = pi, pi " to the right"#

#"Vertical Shift " = D = 3#
