You will see that intervals, returning multiple solutions, are clearly envisioned. I don't see anything indicating multiple solutions, just a single solution occurring in a particular interval. The example shown just shows a single solution. Perhaps when you provide an interval that encompasses more than one valid solution, it gets confused. If you plot that function, you'll notice that it changes slope at x=0, which may confuse the solver. Also, the root at x=2 is unique, since the function does cross the ordinate axis. This is why Solve and Zeros do not list the root 2 twice. |
