What is the maximum and minimum of the vertex?

Excuse me, could you clarify what you mean by "the maximum and minimum of the vertex"? Are you referring to the vertex of a mathematical function, a graph, or perhaps something else entirely in the context of cryptocurrency or finance? If we're discussing a mathematical function or graph, typically, the vertex refers to the point where a parabola or other curved line changes direction, either reaching its highest or lowest point. In that case, the maximum of the vertex would be the highest point on the graph, while the minimum would be the lowest. However, without more context, it's difficult to give a precise answer. If you're referring to a different concept entirely, could you please elaborate on the specific scenario or context in which you're asking about the maximum and minimum of the vertex? That would help me provide a more accurate and relevant response.
