: Polynomial Functions Question 6 (8 points) Saving $ Using what you have learned in this unit, solve the following problem: The profit of a company can be modelled by the polynomial function P() - -1 + 120 -21 + 10. where Pis the profit, in thousands of dollars, and t is the time, in years. When will the company make their maximum profit of $108 000? Question 7 (5 points) Saving. The height of a shotput can be madeled by the function: H( = -690 +ac -1.5 where His the height in metres and ris the time in seconds. ( a) Graph this function using graphing technology. Ensure your axes are properly set up, and state the domain and range that are appropriate for the situation. At what point do you think the shotput was traveling the fastest? What factors did you use to make your inference? Determine the average rate of change on a short interval near the point you chore. (b) Determine the instantaneous rate of change at this point. ()d) Are the rates you calculated in a) and by the same or different? Why do you think this is?
