Polynomial Functions.
vertex: For graphing, the leading coefficient "a" indicates how "fat" or how "skinny" the parabola will be. ... This point, where the parabola changes direction, is called the "vertex". Advertisement. If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).
