vocabulary\nthe range of a quadratic function begins at the value of the vertex.\ncheck

Brief Explanations:

A quadratic function is of the form $y = ax^{2}+bx + c$. The vertex of a quadratic function gives the maximum or minimum value depending on whether $a>0$ (opens up, minimum at vertex) or $a < 0$ (opens down, maximum at vertex). The range of the quadratic function starts from this maximum or minimum value at the vertex.

Answer:

maximum or minimum
