In fact, the bi-exponential equation i described here is a bi-exponential decay equation. The domain of X is 0 to inf. The parameter A and C should be greater than 0 and B, D should be less than 0. I have plotted a simulated data with R. It seems the inverse function of the bi-exponential...

Homework Statement What is the inverse function of a bi-exponential function like the following: Y=A*exp(B*X)+C*exp(D*X) Homework Equations Y=A*exp(B*X) The Attempt at a Solution If it is a single exponential function, i can take log on both sides to get inverse function. But when...
