Trigonometry
Determine the amplitude, period, phase shift, and vertical translation of the given trigonometric function.
y = -(1/8) sin ((1/4)x + π/4)
Amplitude = 1/8, period = 8π, phase shift: π units to the left, vertical translation: none
Amplitude = 1/8, period = 4π, phase shift: π units to the left, vertical translation: none
Amplitude = 8, period = 8π, phase shift: π units to the right, vertical translation: 4 units up
Amplitude = 8, period = 4π, phase shift: 2π units to the right, vertical translation: none
