SOLUTION: The problem is Find the Amplitude, period, and phase shift(s) of the function. f(x)=4cos(x + (pi / 3))

Question 90540: The problem is Find the Amplitude, period, and phase shift(s) of the function.
f(x)=4cos(x + (pi / 3))
Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
f(x) = a*cos(bx + c) + d
a determines amp
b determines period
c determines horizontal shift
d determines vertical shift
f(x) = 4*cos(x + (pi / 3))
Amp: 4
Period: 2/1
Horizontal Shift: /3 left
Vertical Shift: 0
