5.4: Exponential Functions 5) Determine the equation of an exponential function that contains the points (3, 144) and (4, 864) of the form f (x) = 0(1))"- 6) Maike decided to make a risky investment into her favorite cousin's start-up company (she loves her cousin, but is not sure about the company, which gives "history of mathematics" bicycle tours). Maike's nancial adviser ran some data through her software and found the prediction formula A(t) = 350(0.91) t, where A(t) is the predicted value of Maike's investment, in dollars, after t years. a) How much money does Maike initially invest? Include units. b) Does this function represent exponential growth or decay? Explain your reasoning. c) The amount of money in the account increases/decreases (circle) by % each year. d) Evaluate: A0) = e) Interpret your answer to part d) in the context of this situation
