Let  \[f(x) = \left\{ \begin{array}{cl} ax+3, & \text{ if }x\ \textgreater \ 2, \\ x-5 & \text{ if } -2 \le x \le 2, \\ 2x-b & \text{ if } x \ \textless \ -2. \end{array} \right.\] find a+b if the piecewise function is continuous (which means that its graph can be drawn without lifting your pencil from the paper).
