Amplitude

Period

Vertical Translation

#### Explanation:

I would write your function isolating

From this you can "see":

1] The amplitude of your cosine is

2] The period is

3] The vertical translation is given by

Graphically:

graph{4cos(x/2)-2 [-16.02, 16.02, -8.01, 8.01]}

As you can see you have a cosine oscillating between
