14] In economics, functions that involve revenue, cost and profit are used. Suppose R(x] and C(x)
denote the total revenue and the total cost, respectively, of producing a new high-tech widget. The
difference P(x) = R(x) - C(x) represents the total profit for producing x widgets, Given R(x) = 60x -
