Question 1111331: i would like to ask how to find the decay rate in the exponential decay formula

Answer by math_helper(2461)   (Show Source): You can put this solution on YOUR website!

If your decay function has this form:


then you will need two points for x,y in order to solve for constants A and k. You will want
to take logs of both sides to make the equations linear:
ln(y/A) = -kx
