Given that an equation, $y=2+3x-x^3,$ has no asymptotes, complete the table $($the unshaded blocks$).$ Sketch the graph. If you prefer not to use the table, list the intervals where the function is increasing$/$decreasing$,$ where the function is concave up$/$down$,$ the points where a relative max and$/$or min occur, and any points of inflection. Given $y^{\text{'}}=3-3x^2$ and $y^{\text{'}\text{'}}=-6x.$
