Plz help this is complicated

Answer 1

Answer:

Graph attached.

Step-by-step explanation:

In the question the given parameters are as followed.

$y=7cos(\frac{x}{2})+1$

1). Amplitude a = 7

2). Period = $\frac{2\pi }{\frac{1}{2}}=2\pi \times 2=4\pi$

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.
