Abiologist 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) = 11(1.01)d

part a: when the biologist concluded her study, the radius of the algae was approximately 11.79 mm. 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(d) represent? (2 points)

part c: what is the average rate of change of the function f(d) from d = 2 to d = 7, and what does it represent? (4 points)
