I am having difficulty understanding the difference between a vertical tangent or a cusp, and when they each occur. Can someone please describe to me the difference between the two and when you know they happen? Provide examples please. Thanks!

consider two curves ...
has a vertical tangent and an inflection point at x = 0
has a cusp (a vertical tangent from both sides of x = 0), but no inflection point at x = 0
