SOLUTION: F(x)= 4cos2(x-45�) where x is in degrees, what is the amplitude and shift

Question 1053654: F(x)= 4cos2(x-45�) where x is in degrees, what is the amplitude and shift
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
The amplitude is 4, since that is the leading coefficient, and the phase shift is C/B, where C is 45 degrees, and B as written, is 1. 45 degrees.
F(x)=Acos f(Bx-C)+D; A is the amplitude and C/B is the phase shift.
