It is slightly parabolic which we are not identified.

Because it sf is the area of the triangle(varying load), @fixed end load = w, using similarity of triangle load at any section x-x from a distance x from free end we get wx/l so total load @between section xx and free end = area of triangle(gradually varying load) = 1/2wxx/l = wx^2/l(parabolic curve).
