Answer:
Graph attached.
Step-by-step explanation:
In the question the given parameters are as followed.
[tex]y=7cos(\frac{x}{2})+1[/tex]
1). Amplitude a = 7
2). Period = [tex]\frac{2\pi }{\frac{1}{2}}=2\pi \times 2=4\pi[/tex]
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.
