Trigonometry
Determine the amplitude, period, phase shift, and vertical translation of the given trigonometric function.
y = 2 sec (πx/2 - 4π)
Amplitude: None, period = 4π, phase shift = 8 units to the right, vertical translation: 4π units up
Amplitude: None, period = 4, phase shift = 8 units to the right, vertical translation: none
Amplitude: 2, period = 4, phase shift = 8 units to the left, vertical translation: none
Amplitude: None, period = 4, phase shift = 4π units to the right, vertical translation: none
