As below.

#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]}
