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.
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).
Finding the vertex of a parabola in standard form. Google Classroom. About. Transcript. Sal rewrites the equation y=-5x^2-20x+15 in vertex form (by completing the square) in order to identify the vertex of the corresponding parabola.

noun. , plural ver·tex·es, ver·ti·ces [vur, -t, uh, -seez]. the highest point of something; apex; summit; top: the vertex of a mountain. Anatomy, Zoology. the crown or top of the head. Craniometry. the highest point on the midsagittal plane of the skull or head viewed from the left side when the skull or head is in the Frankfurt horizontal.
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.
A vertex is a corner. An edge is a line segment between faces. A face is a single flat surface. Let us look more closely at each of those: Vertices. A vertex (plural: vertices) is a point where two or more line segments meet. It is a Corner. This tetrahedron has 4 vertices. And this pentagon has 5 vertices: Edges. This Pentagon. Has 5 Edges.
A vertex (vertices for plural) is a point at which two or more sides or edges of a geometric figure meet. Vertex of an angle. The vertex of an angle is the common endpoint of two rays that make up the angle's sides. The vertex for angle BAC, written ∠BAC, is point A. The angle can also be named as ∠CAB or by only its vertex, ∠A.
