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