    False. If f(x) = x, then the derivative is 1 at all points, including the point x = 0.

      good answer; also, in a two-dimensional Cartesian Plane, f(x) is the straight line containing the point (0,0) with slope = 1

      Since that is pure gibberish I would skip it. Unless they used a curvy x to mean |x| in which case w.o.w.

    You meant f(x) = |x|?

    Derivative jumps from -1 to 1 in 0 distance.

    Of course you already googled it so do you have a specific question?
