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:
Left side of graph of function would be up .
Step-by-step explanation:
Given :
.
To find : In which direction does the left side of the graph of this function point.
Solution : We have given that
.
We can see from the given function Degree is even and leading coefficient is positive .
By the behavior of end points : left side of graph would be up .
Therefore, left side of graph of function would be up .
