Answer:
6(3)-3
Step-by-step explanation:
Answer:
(a) Amplitude = 4
(b)
--- Period
(c)
--- phase shift
--- vertical shift
Step-by-step explanation:
Given

Rewrite the function as:

Solving (a): The amplitude
A cosine function is represented as:
![f(x) = A\cos[B(x - C)] + D](https://tex.z-dn.net/?f=f%28x%29%20%3D%20A%5Ccos%5BB%28x%20-%20C%29%5D%20%2B%20D)
Where:

So, in this equation (by comparison):


<em>The amplitude is 4</em>
Solving (b): The period (T)
This is calculated as:

By comparison:

So:

Solving (c): The shift
The phase shift is C
The vertical shift is D
By comparison:
--- phase shift
--- vertical shift
