Problem
A function g is continuous on (0,6) and differentiable at every point in that interval except possibly where noted. Its graph has a horizontal tangent at x=2, a vertical tangent at x=4, and no other points in (0,6) where the tangent is horizontal or vertical. List all x-values in (0,6) that are critical numbers of g.
