WebNov 9, 2024 · If a ramp function would be shifted anywhere to the left/right on the x-axis, its apex point would occupy an actual point space on an x-axis and the absolute value of this point on an x-axis should probably provide a non-zero time. In theory such a point of absent derivative occupies a space on x and y axes.
