The effect of k on exp(kx), exponential growth and decay

The graph of the exponential function [math]e^{kx}[/math] is displayed. You change the values of [i][math]k[/math][/i] and observe how the exponential growth or decay graph changes. As the absolute value of [i][math]k[/math][/i] increases, the rate of growth/decay intensifies.
