**Conics Parabolas Introduction Purplemath**

When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry. • the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0). • the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).... This equation,,is in Standard Form and is called the vertex form of the parabola. Looking at the GSP construction and the vertex form of the parabola, we can use the GSP construction and the vertex form of the parabola to find the vertex , focus , and directrix, in addition to …
