Answer:
B
Step-by-step explanation:
Given a sinusoidal function in the form , we can say:
- A is the amplitude
is the period
is the phase shift
- D is the vertical shift
From the function given m(t) = 7 Cos (t+3), we see that
A = 7
B = 1
C = 3
D = 0
Thus, from the info, we can say
Amplitude = 7
Period = 2π
Phase Shift = -3
Vertical Shift = 0
Answer choice B is right.
