Determine the amplitude, period, phase shift, and vertical translation of the given trigonometric function.
y = 3 + 5sin(x/7)

• A. Amplitude = 5, period = 14π, phase shift: none, vertical translation = 3 units up
• B. Amplitude = 5/2, period = 14π, phase shift: none, vertical translation = 3 units down
• C. Amplitude = 5, period = 2π, phase shift: π/2 units to the right, vertical translation = 3 units up
• D. Amplitude = 5, period = 2π, phase shift: none, vertical translation = 3 units down

Answer: (A)
