Tutorial on finding the domain, range and vertical asymptotes and graphing logarithmic function

A website where Exponential functions are explored, interactively, using an applet. The properties such as domain, range, horizontal asymptotes, x and y intercepts are also investigated. The conditions under which an exponential function increases or decreases are also investigated.

This website tells you about exponential functions, and also has a interactive program that allows you to see a graph and change the points on the coordinate plane which changes the graph. This is very helpful in knowing how the graph works.

There are many practice problems on this website. You can actually click and try to do the problems. There are instructions on the top of the page to inform how to use the website.
