A market analyst working for a small-appliance manufacturer finds that if the firm produces and sells x blenders annually, the total profit (in dollars) is
P(x) = 8x + 0.3x^2 − 0.0013x^3 − 379.
Graph the function P in an appropriate viewing rectangle and use the graph to answer the following questions.
(a) When just a few blenders are manufactured, the firm loses money (profit is negative). (For example, P(10) = −270.30, so the firm loses $270.30 if it produces and sells only 10 blenders.) How many blenders must the firm produce to break even?
