Forecasting Profits As a result of increasing energy costs, the growth rate of the profit of a 4-year old glassblowing company has begun to decline. The company's management, after consulting with energy experts, decides to implement certain energy-conservation measures aimed at cutting energy bills. The general manager reports that, according to his calculations, the growth rate of their profit should be on the increase again within 4 years. If the glassblowing company's profit (in hundreds of dollars) t years from now is given by the function P(t)=t38t2+45t+50(0t8) determine whether the general manager's forecast will be accurate. Hint: Find the inflection point of the function P and study the concavity of P. Yes, the forecast will be accurate. No, the forecast will not be accurate
