By default, the function on the left is [math]f(x)=e^x[/math] and the function on the right is [math]g(x)=2^x-x^3+\sin(10x)[/math]. The purpose of this applet is to demonstrate that the ideas for graph transformations are not unique to the six basic trigonometric functions. Go ahead and replace either [math]f[/math] or [math]g[/math] with [math]sin(x)[/math] and see that the [math]a[/math] slider does a vertical stretch of BOTH graphs in exactly the same way.
