1. The problem statement, all variables and given/known data Ok, so I have an unknown exponential function: y1 = f1(t) By measuring the values of t and yi, a linear connection is generated between Yi (=log (yi)) and t: Yi = Ait + Bi. A1 = -2.12 B1 = 1.96 Problem 1: Describe f1 in the following matter: y1 = f1(t) = Ceλt 3. The attempt at a solution I've been juggling with numbers and letters without ending up with anything reasonable. Ok, let's ramble down some thoughts: Adding log function to both sides of the functions gives log(y1) = log t + log -2.12 + log 1.96 = log (C) + log (e) λt And this is where it all ends. Any help out there? Would be much appreciated!
