Explore interactively, using an applet, rational functions and the properties of their graphs such as domain, vertical and horizontal asymptotes, x and y intercepts.

This site explains step-by-step how to graph rational functions and how to find the asymptotes and x and y intercepts.

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.

Explains what it is and its formula

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.

The site gives steps on how to graph the functions. There are many examples worked out to demonstrate. There are a few graphs shown on the website. At the bottom there are other links for exponential functions.

The site gives the definition of a ploynomial. It has many examples graphically on what the functions could possibially look like. It also shows how to fing the exponents and leading coeffecient. At the bottom there is a section where it ask many question and you can type in your answer.

This website gives many demos of what average rate of change actually is. It tells the formula for how to find it and gives many examples. The site also has many graphs on it to show what average rate of change looks like graphically.

This site defines the meaning of domain and range. It also shows how to find domain and range by looking at a function. It gives many examples and works the probelems. There is also a link for more domain and range problems on the page.
