Problem 1: Average Value Problem 1 Suppose you are interested in investing in a particular mutual fund. You research the annual rate of return ofthe fund layer the past 5 years and nd the following graph: Note that the 1.rertical axis {R5 represents the percentage annual return,I and the horizontal axis [t] represents time measured in yea rs. Assume that t=5 represents the present day and that t=EI represents 5 years ago. a. Based on the graph, does it appear that the average annual rate of return is at least 3%? How can you tell'r1 Describe your answer based on what you learned in this week's reading or by proyiding a sketch. b. The graph ofthe annual percentage rate of return by the function shown above an be approximated by the equation t]- = it: + I:2 2: + 3. Using this function. compute the average rate of return for the past 5 years. For full credit, he sure to show your work carefully
