Plz help this is complicated

Answer 1

Graph attached.

Explanation:

In the question the given parameters are as followed.

`y=7cos((x)/(2))+1`

1). Amplitude a = 7

2). Period =
`(2\pi )/((1)/(2))=2\pi * 2=4\pi`

3). Vertical shift = 1 means mid line of the graph will be y =1 and maximum of the graph is 8 and minimum is -6.
