Exponential Function Graphing Calculator

This draws an exponential curve over a range of x you choose. Enter the coefficient, the base, the horizontal shift and the vertical shift, or set the base to e, and it plots the curve with the horizontal asymptote, the y-intercept and the x-intercept marked, beside a table of values. It also reports which way the curve runs, the percentage change per unit of x and the interval over which the power term doubles or halves. An exponential outruns any window, so when the values grow too fast to show the vertical view is cut back and the table carries the rest.
