Project on blackboard. Trace/Connect max/min points with a smooth curve. Measure successive heights. Determine the rate of decay. Find the correct exponential decay function. Use graphing software to superimpose the function they find on top of the function draw on the board. Change parameters and repeat process. Could be worthwhile.

An online tool that graphs multiple functions. Graphs can be linked to by URL, or downloaded as images (for use in tests/worksheets!). Can adjust window and zoom, but can not yet change graph/grid colours and scale is at the edges of the window rather than on the axes. Still in development, so may have features added in the future.

An online graphing calculator with great visual presentation. Nice thick lines for projection. Implicit graphing. Easy tracing. Mulitple functions (and relations!) graphed at once. It looks like this tool is under ongoing development, and a committment to remain free. This one is a keeper.

I found it difficult to enter the equations, the keyboard keeps disappearing and keeps blocking the equation. Any hints..?

A good exercise comparing exponential functions.

An incredible resource! 68 lessons from functions (a touch of grade 11 but mostly grade 12) to university calculus. Tons for MCV. Make sure to link to this from your moodle!

Stats Can data sorted by the type of relation it approximates - linear, quadratic, logs, sinusoidal, exponential, cubic, combined,
