WebRemovable discontinuities are characterized by the fact that the limit exists. Removable discontinuities can be "fixed" by re-defining the function. The other types of discontinuities are characterized by the fact that the limit does not exist. Specifically, Jump Discontinuities: both one-sided limits exist, but have different values. WebThat is. g ( x) = x − 1 = { ( x − 1) 2 x − 1 x ≠ 1 0 x = 1. is a differentiable function. As you said, the existence of a limit at a point (even along with differentiability in the neighborhood of that point) does not guarantee that the function is differentiable at that point. In order for a function to be differentiable at a point, it ...
