The amplitude is $2$ The period is $2$ The vertical translation is 0 The phase shift is $2$

$y = A~sec(Bx+C)+D$ $y = 2~sec(\pi x-2\pi)$ $A = 2$ $B = \pi$ $C = -2\pi$ $D = 0$ $\vert A \vert$ is the amplitude. The amplitude is $2$ $\frac{2\pi}{B}$ is the period. The period is $2$ $D$ is the vertical translation. The vertical translation is 0 $\frac{-C}{B}$ is the phase shift. The phase shift is $2$
