1. (20 points) Attempt to take the back transform of these Laplace functions using the finger-print method. If this is not possible state your reason.

2. (10 points) Write the differential equations, take the Laplace of these equations, rearrange them to solve for L(X₁) and solve for X₁ given the pharmacokinetic model below. K0 is zero order and all other rate constants are first order.
