**Section 4.1 – Exponential Functions**- online resources:
- The Exponential Function I - http://members.shaw.ca/ron.blond/TLE/ExpFcn.APPLET/

This site provides a java applet which graphs*y*= a*b^{x}with sliders to see what happens to the graph when a and b change. - The Exponential Function II - http://mathinsite.bmth.ac.uk/applet/exponential/exp.html

This site provides a java applet which graphs*y*= A + B*e*^{kx}with sliders to see what happens to the graph when A, B and k change. - Function Plotter - http://www.univie.ac.at/future.media/moe/fplotter/fplotter.html

After entering one or more functional expressions, the graphs are drawn. Using the zoom option, you may study the graphs from a very "close" viewpoint and read off coordinates of interesting points with an accuracy of about 10^{-14}.
