Let P(t) represent the price of a share of stock of a corporation at time t. What does each of the following statements tell us about the signs of the first and second derivatives of P(t)? (a) "The price of the stock is rising faster and faster." (b) "The price of the stock is close to bottoming out." My answers: (a) P'(t) > 0, P''(t) > 0 (b) Does anyone know what "bottoming out" means? I never dealt with the stock market. If i knew what that term meant, I'm sure I could figure it out.
