Algebra: f'(x) results in NDerivative, not the actual analytic derivative

Not a Problem

I used to be able to specify a function, say e.g., f = 5x^2 + 2x - 1 and then enter f' in Algebra mode and it gave me the analytic derivative expression on the left along with the graph of the derivative on the right.

Geogebra seems to no longer do that. Instead I get the "result" NDerivative(f) on the left (but still plots the graph on the right).

Were analytic derivatives disabled or am I doing something wrong?

I can't see your issue both in v.5 and v.6 classic.

I've entered

 f(x) = 5x^2 + 2x - 1
then

f'
in the following line.

Can you add your file or a screenshot, and tell us which version of ggb are using, as well as the OS?

Please use GeoGebra Classic if you want that to work; we're removing symbolic commands from Graphing/Geometry/3D for compatibility with exams
