I have to work out the exponential decay using the formular y=ka^-mx +c but i am not even sure where to begin. Can anyone offer some help please.
Enter your data into Excel, then in the toolbar click on Insert, then Chart.
XY scatter, enter your data into the box and create your chart. Then,
click on Chart, Add Trendline, Click on the Options tab and make sure that
"Show equation on Chart" is checked. Also, check R^2. The closer it is to 1,
the better.
