how would you go about drawing the graph of a functions derivative, if the original function is unknown. IE only the graph if F(x) is given but not the equation.

thanks

A kink will imply a discontinuity in the derivative, and a vertical asymptote will mean the same thing in the derivative.

I hope this just about covers most situations.

"You could construct the tangent at different points..."

should read:

"You could construct and plot the magnitude of the tangents at different points..."
