hi all,

how would the graph of y=2 cos x + 2 on the domain 0<=x<=2Pi would look?

You should know the basic shape of the cosine graph. The period is $\displaystyle \displaystyle \begin{align*} 2\pi \end{align*}$, the amplitude is 2 which means the basic graph is stretched by a factor of 2 vertically, and the mean value is 2, so the graph is moved up by 2 units.
