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
.
Answer:
The answer is C . (5x^3-7)(2x^2+1)
