# Quadratic Function HTML5 applet - Vertex form

An html5 applet to explore the properties of quadratic functions in vertex form. The parameters $a$, $h$ and $k$ included in the definition of a quadratic function of the form $f(x)=a(x-h)^2+k$ may be changed and therefore the graph of function $f$ explored. We may explore the vertex, the x and y intercepts, shifting, etc ... using this applet.
 a = 1 -10+10 h = 0 -10+10 k = 1 -10+10
