(03.08 HC) Belinda is thinking about buying a car for $45,000. The table below shows the projected value of two different cars for three years. Number of years 1 2 3 Car 1 (value in dollars) 40,500 36,450 32,805 Car 2 (value in dollars) 42,000 39,000 36,000 Part A: What type of function, linear or exponential, can be used to describe the value of each of the cars after a fixed number of years? Explain your answer. (2 points) Part B: Write one function for each car to describe the value of the car f(x), in dollars, after x years. (4 points) Part C: Belinda wants to purchase a car that would have the greatest value in 13 years. Will there be any significant difference in the value of either car after 13 years? Explain your answer, and show the value of each car after 13 years. (4 points)

(03.03 MC) A marine biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months: f(m) = 3(1.09)m Part A: When the marine biologist concluded her study, the length of the fish was approximately 5.98 cm. What is a reasonable domain to plot the growth function? (4 points) Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points) Part C: What is the average rate of change of the function f(m) from m = 2 to m = 8, and what does it represent? (4 points)
