Solving equations with predefined functions
Needs Answer
I have a function f(x) defined by FitExp.
Then in CAS, I want to Solve[f(x) = 100], but it gives the answer x=?.
How should I solve this equation?

Followup! It works fine if I don't restrict 0 <= x <= 50. But since the solution is within this interval, it's strange that it wouldn't find it.
This seems to be a bug, unless there's some usecase I'm missing.
It works with this list.
Very curious. Could it be a version difference between the Windows and OSX editions?
But it did now work with your numbers in newest 5.0.352 on Mac. So there is something wrong.
