ANSWER

To graph the function

$y=4cos(x)$ we need to plot some few points within one period. Since the interval is not given, we shall use $[0,2 \pi]$ '

$\left \begin{array}{cc}x&y=4cos(x)\\0 &4\\\frac{\pi}{2}&0 \\ \pi&-4\\\frac{3\pi}{2} &0\\2\pi&4\end{array}\right$ .

We plot the above points to obtain the graph as shown in the attachment.

Answer:y =-9,-8,-7,-6,-5

Step-by-step explanation:

Is this what you need? To find the y values you take an x value and subtract 7. Like the first one -2 would turn into -9
