marking the break visually in the graph in a non-continous function?
I have to graph some functions that like this one are non-continuous.
Now, Geogebra plots this all fine, but in the math book (and probably in the results I have to send in) they would like me to mark the break point with arrowheads on the function line. So that two arrowheads oppose each other and the tips are the break point in the function.
I know where the point is, when calculating ex. f(1) it returns "undefined" and it obviously doesn't want to set a point A there ;)
Is this possible to do in Geogebra? I have not found a setting in the function settings that allows me to do it. I have found a "line style setting" where I can select different arrowheads but this seems not to be a solution to my problem.
