Hmm, really!??
Here's a slightly different approach:
Unfortunately the more direct and logical
does not work in Mathcad - muPad is not capable to find the solutions.
Hi,
Set a function that is the derivative of f(x).
Use the root function on this derivative within a range to determine unique roots.
You now have enough info to plot the points.
Many thanks both of you, Valery. And I still have a query : "How to prove what point is local min-point ?
Best Regards.

Some basic calculus (see Werner's application):
In case of this function Mathcads symbolics is capable enough to give you al solutions, so you should use it.
If your goal is to limit the results to x1<x<x2 you may use the "assume" modifier.
