Mathematica uses an internal algorithm to adjust the plot range to show what it considers the most interesting area of the plot. As A consequence, this clips regions you may be interested in. This can be defeated by explicitly setting the plot range so the region you are interested in is plotted. Specifically,
Plot[{x^3 - 6x, 8 - 3x^2}, {x, -5, 4}, PlotRange->All]
will show the intersection point at {-4,-40}
