This applet will illustrate the composition of two functions, f(x) anf g(x).[br][br]You can display two functions by using the show check box for each equation. The default equations are [math]f(x) = x^2[/math] and [math]g(x) = -2x[/math], you can enter equations of your choice by entering the function of x of your choice.[br][br]Functions f(x) will graph in [color=#c51414]red[/color], and g(x) will graph in[color=#0a971e] green[/color]. [br]The composition will displayed as h(x)= f[g(x)] and will display in [color=#1551b5]blue[/color]. [br]By clicking on the appropriate check box, you will be able to display each graph separately or together.[br][br]
