![\bf f(x)=\stackrel{A}{-3}cos(\stackrel{B}{2}x\stackrel{C}{-\pi })\stackrel{D}{+2}~~ \begin{cases} C=-\pi \\ B=2\\ \frac{C}{B}=-\frac{\pi }{2}&\qquad \stackrel{\textit{horizontal shift}}{\frac{\pi }{2}\textit{ to the right}}\\[-0.5em] \hrulefill\\ D=+2&\qquad \stackrel{\textit{vertical shift}}{2\textit{ upwards}} \end{cases}](/tpl/images/0020/3083/0df47.png)
