Answer
I would expect it to be given by the profit polynomial divided by the revenue polynomial. Since both of the functions are polynomials of the same degree (3), we will likely obtain a relatively flat function which increases slowly.
Work Step by Step
In a, we were asked to explain how the two teams could work together to create a profit margin function. Now, in part b, we are asked to give a general description of what the answer would be, without actually solving for it. From a, we know that the profit margin function will most likely contain the profit function divided by the revenue function. Since both of the functions are polynomials of the same degree, we will likely obtain a relatively flat function.
