As below.

Explanation:

y = A sec (Bx - C) + D

"Given : " y = -3 sec (2pix - (pi/4))

"Function : sec (x) doesn't have amplitude"

"Period " = (2pi) / |B| = (2pi) / (2pi) = 1

"Phase Shift " = -C / B = (pi/4) / (2pi) = 1/8, " 1/8 to the right"

"Vertical Shift " = D = 0

graph{-3 sec (2pix - (pi/4)) [-10, 10, -5, 5]}
