I'm looking to design a question where students sketch a derivative based on a drawn function without the y-axis.
The y-axis is not important as we're focusing on the x-values of turning points and inflection points (in fact I don't need it at all).
I haven't managed to find a way to graph a function with only the x-axis (without the ticks or numbers is even better) with tikz or pgfplots.
Does anyone know how to do this?
Thanks in Advance!
