nRoot - bug?

By defining f(x)=nRoot(x,3) a gap appears in the graph just to the left of the origin (if you don’t see it immediately, zoom a lot). If you increase exponent of x, you don’t need to zoom as much. Is this a bug?

You need to zoom a little. Try f(-5E-9) in Input bar. I think it is a bug.

I can replicate the bug in my Mac with newest GG5, GG6 and Graphing Calculator in my Chrome.

Thanks, we'll check. In the meantime use cbrt() :)

And it is possible to draw the plot using fractional powers, too. (If you don't care about the domain of the function.)
