Process efficiency is a measure of the ratio of process outputs to inputs.
Answer:

Step-by-step explanation:
Rewrite the differential equation as:

Integrate both sides with respect to x:


Integrate one more time both sides with respect to x:


Now that we find the solution, let's find its derivate:

Evaluating the initial conditions:


Replacing the value of the constants that we found in the differential equation solution:
