1. For the cost function, find the marginal cost at the given production level x. State the units of measurement. (All costs are in dollars.) HINT [See Example 1.] C(x) = 15,000 + 10x + 1,000 x; x = 100

2. Find the marginal cost, marginal revenue, and marginal profit functions.

C ( x ) = 5 x ² ; R ( x ) = x ³ + 7 x + 12

Marginal cost

Marginal revenue

Marginal profit

Find all values of x for which the marginal profit is zero. Interpret your answer. (Enter your answers as a comma-separated list.)
