As Below.

$y = (1/2) sec ((pi/2)x)$

Standard form is $color(red)(y = A sec (Bx - C) + D$

$Amplitude = |A| = color(red)("NONE") " for secant function"$

$"Period " = (2pi) / |B| = (2pi) / (pi/2) = 4$

$"Phase shift " = -C / B = 0$

$"Vertical Shift " = D = 0$

graph{(1/2) sec ((pi/2) x) [-10, 10, -5, 5]}
