Equation for controlled fade



Hi,

I'm sure I'm being dumb but I can't think of a way to solve this. Any
help appreciated.

Given three given values of "Start", "End" and "Length", I need a
function for variables time "T" and values "X" where at T = 1 X=Start
and at T=Length X=End. However if you graph T and X (T along the Y axis
and X along the X axis) I'd like the graph to look something like the
graph of 1/X, i.e. an exponential like "fade" from Start to End over T
periods.

Hope this makes sense - any ideas appreciated!

Nick
