## vertex

### In mathematics, a vertex is a point where two or more lines, curves, or edges meet

In mathematics, a vertex is a point where two or more lines, curves, or edges meet. It is also commonly used to describe a point of intersection or a corner of a geometric shape.

In a graph, a vertex refers to a point or a node. It is typically represented by a dot or a circle and represents an object or an element in the graph. Each vertex can be connected to one or more other vertices by edges, forming a network or a graph structure.

For example, in a triangle, each of the three corners is a vertex where two sides intersect. Similarly, in a cube, each of the eight corners is a vertex where three edges meet.

In algebra and calculus, a vertex is often associated with a parabola. For a quadratic function in the form of y = ax^2 + bx + c, the vertex represents the point where the parabola reaches its minimum or maximum value. The x-coordinate of the vertex can be found using the formula x = -b / (2a), while the y-coordinate can be obtained by substituting the x-coordinate back into the equation.

Understanding the concept of a vertex is crucial in various areas of mathematics, including geometry, graph theory, and algebra, as it helps describe and analyze the properties and relationships of shapes, graphs, and functions.
