Sequences of functions

The underlying JavaScript code

<jsxgraph width="600" height="400" box="box">
var brd = JXG.JSXGraph.initBoard('box', {axis:true, originX: 100, originY: 340, unitX: 400, unitY: 200});
var n = brd.createElement('slider',[[0.1,1.5],[1.1,1.5],[1,1,100]],{name:'n'});
var f = function(x){ return Math.pow(x,Math.floor(n.Value())); }
var plot = brd.createElement('functiongraph',[f,0,1], {strokeWidth:1});
brd.createElement('text',[0.2,0.7,function(){return 'f(x)=x<sup>'+Math.floor(n.Value())+'</sup>';}],
  {fontSize:'20px'});
</jsxgraph>
