The textbook says to input nDer(f(x),x) but I can't seem to figure it out. I've tried various things and sometimes it comes out as a line at y=0 but most of the things I've tried don't graph anything at all. Can someone explain to me how to graph a derivative of a function, such as f(x)= lnx?

Two ways, you'll need the derivative template [Template Key, 1st row, 4th column]

Let d represent the "curvy derivative symbol".

Textbook entry:

F1(X) = LN(X)
F2(X) = (d F1(X))/(dX=X)

or directly:
F1(X) = (d LN(x))/(dX = X)

Algebraic Entry:
F1(X) = d( LN(X), X=X)
