I was reading this article in wikipedia related to saddle points. When I came across this line
In one dimension, a saddle point is a point which is both a stationary point and a point of inflection. Since it is a point of inflection, it is not a local extremum.
Actually, I didn't get it when it said that it could also be a point of inflection. Can anyone give me an example of such a function and its saddle point which is both a stationary point and point of inflection?
