For each function, give the amplitude, period, vertical translation, and phase shift, as applicable.

y = 2 sec(πx - 2π)

Graph each function over a one-period interval.

y = csc (x - π/4)

Graph each function over a one-period interval.

y = sec (x + π/4)

Graph each function over a one-period interval.

y = (1/2) csc (2x + π/2)

Graph each function over a one-period interval.

y = 2 + 3 sec (2x - π)
