Trigonometry
Determine the amplitude, period, phase shift, and vertical translation of the given trigonometric function.
y = 18 sin (x + π/7)
Amplitude = 9, period = 2π, phase shift: π/7 unit to the right, vertical translation: 1 unit up
Amplitude = 9, period = π/2, phase shift: π/7 unit to the right, vertical translation: 1 unit up
Amplitude = 18, period = 2π, phase shift: π/7 unit to the left, vertical translation: none
Amplitude = 18, period = π/2, phase shift: π/7 unit to the left, vertical translation: none
