So I think you are right. Where did you get this question from? It seems that "the answer" you have been provided with is incorrect.

Note that (0,0) is not actually a turning point. It's a horizontal point of inflection.

Turning points are local extrema, not horizontal inflections.

Stationary points can be local extrema OR horizontal points of inflection.

O right, thanks, do you follow any steps when graphing: like limit to the asymptotes, even or odd, dividing regions etc. I get really confused when graphing these stuff?
