Let be a function such that f(-1) = 3 and f(2) = -4. Give the coordinates of two points on the graph of a. y = f(-x) b. y = -f(x)

L16 - 8 An Example from Economics The total cost of producing x units of a product is called the cost function C(x). Average rate of change of cost as the number of items produced increases from x 1o x 2 Marginal Cost ex. Suppose the cost function for a certain product is given by C(x)=1 00+2 5 x − 0.1x . 1) Find the total cost of producing 100 items. 2) Estimate the marginal cost at the production level of 100 items.
