Exponential and Log Function Resources
Exponential growth: PaperTearing
Exponential decline: The Ozone Layer
The exponential chapter of Graphic Algebra takes students through a variety of tasks begining with a simple double function in a paper tearing context and moving through to looking at population doubling times around the world.
A supplement to introduce the use of the symbolic features of the TI89 is provided here for Paper Tearing and Ozone Layer problems.
A pre-test and post-test are also available.
Exponential and Log Transformations
Four spreadsheets developed by Alan Benetto at Westbourne Grammar School that show transformations of the exponential and log functions.
