Ответ:
(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:
Where:
So, in this equation (by comparison):
The amplitude is 4
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
