A function [math]f(x)[/math] is said to be [math]O(g(x))[/math] if there are constants C and k such that [math]f(x) \leq C g(x)[/math] for all [math]x > k[/math]. This applet helps you visually classify various functions as [math]O(x^n)[/math].
For each function with a checkbox, adjust the values of C, n, and k to find a comparison power function [math]Cx^n[/math] so that the function you checked is below [math]Cx^n[/math] for all values to the right of k.
