Trigonometry
Determine the amplitude, period, phase shift, and vertical translation of the given trigonometric function.
y=6cos(π3(x−15))y=6\cos\left(\frac{\pi}{3}\left(x-\frac15\right)\right)
Amplitude = 6, period = 6, phase shift: 15\frac1551 unit to the left, vertical translation: none
Amplitude = 6, period = 6, phase shift: 15\frac1551 unit to the right, vertical translation: none
Amplitude = 3, period = 23\frac2332, phase shift: 5 units to the left, vertical translation: 3 units up
Amplitude = 3, period = 32\frac3223, phase shift: 5 units to the right, vertical translation: 3 units up
