Vertex is a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet. The plural of a vertex is vertices. For example, in the above figures, points A, B, C, D, and E are vertices. History.
noun. ver· tex ˈvər-ˌteks. plural vertices ˈvər-tə-ˌsēz also vertexes. Synonyms of vertex. 1. : the top of the head. 2. a. : the point opposite to and farthest from the base in a figure. b. : a point (as of an angle, polygon, polyhedron, graph, or network) that terminates a line or curve or comprises the intersection of two or more lines or curves.
In geometry, a vertex (pl.: vertices or vertexes) is a point where two or more curves, lines, or edges meet or intersect. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.
Finding the vertex of the quadratic by using the equation x=-b/2a, and then substituting that answer for y in the orginal equation. Then, substitute the vertex into the vertex form equation, y=a(x-h)^2+k. (a will stay the same, h is x, and k is y).

About the vertex, the vertex is determined by (x-h)² and k. The x value that makes x-h=0 will be the x-coordinate of the vertex. K will be the y-coordinate of the vertex. y=-10(x+4)²-3 This will have a vertex at (-4,-3). a is negative therefore will open down and have a maximum point. |-10| > 1 therefore it's really skinny.
