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.
