Step-by-step explanation:
Given:
Amplitude = 2
Midline = 5
Period of 
.
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude, 
is period, 
is phase shift and D is the mid line.
Period of function is . So,
Substituting 
in (i), we get
Therefore, the required cosine function is .
