Extrema bepalen lukt niet

Beste

het lukt me niet om van sommige functies de extrema te bepalen.

Bij een vorige versie van Geogebra lukte dit wel.

Bug in het programma?

Only extrema of polynomial are calculated with a syntax like Extremum(f).

Since your function is irrational, you need to enter also a guess interval for your extrema, like e.g. (-2,2)

See my file and https://wiki.geogebra.org/e...

So you can't use the Extremum button, but have to enter the command?

That answers my problem,

but too bad my student aren't able to use the button.
