However , I’m not really sure how to get the answer so if you could explain it step by step that would help a lot. Thanks! the price per unit drops to $75.a. Express the price per unit p as a function of the order size z.b. Express the profit P as a function of the order size z.Restricting the Domain In Exercises 77, 78, 79, 80, 81, 82, 83, and 84, restrict the domainof the function f so that the function is one-to-one and has an inverse function.
