Answer:
i simplified it but its not simple i dont know the answer so i cant help you
Answer:
c
Step-by-step explanation:
The general function for the cos function is:
<span>y=Acos<span>(B<span>(x+C)</span>)</span></span>
where A
is the amplitude, <span><span>2π</span>B</span>
is the period
and phase shift is C
.
For our function: f(x) = −4 cos(3x − π) + 1 =-4cos(3(x-π/3))+1
the amplitude is:-4
the phase shift is: -π/3
