Posted on Apr 22, 2010
Topic: Exponential Functions
Students move a point that changes the value of the exponent x in an exponential function f(x) = bx and see the corresponding point on the graph as well as the value of f(x).

Students compare exponential functions with the base greater than one and the base between zero and one. Students will describe the domain and range of such exponential functions.
The goal is for students to make the connection that exponential functions with a base larger than one will have graphs that increase while exponential functions with a base between zero and one will have graphs that decrease.
