Am I thinking right about this following question:
Give a geometric argument to show that the graph of y = lxl has no tangent line at the point (0,0).
Since that graph would be basically the bisectors of the 1st and second quadrants, why can't the x-axis be that tangent line?
(def. of a tangent line is a line that touches the graph at one point, which is the origin in this case)
thanks
