A parabola with vertex (3,k)
This is, y = a(x-3)^2 + k
Because the symmety axis of a parabola passes trough its vertex.
vertex is a point where the lines meet for example the square has 4 corners each corner is called a vertex.
Vertex is also sometimes used to indicate the top or high point of something.
