A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function?
Part B: What does the y-intercept of the graph of the function f(d) represent?
Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?
